|Not DNS related, but a PSA... did you know the EPA mandates your local water be tested and those results be made available to you? I learned my water company published this data which contains numerous carcinogens and some registered radioactivity that is being fed to the region. Check yours, and respond appropriately to protect you and your family. Much of the contamination is not on purpose, there's no conspiracy, but is still an issue. Take advantage of the data in your area to make well informed decisions.|

|mooo.com was yanked from freedns.afraid.org by the registrar this AM. I was able to re-acquire delegation again very rapidly and sort out the details with the registrar and confirm delegations were corrected around 11AM today. A users site on this domain created the issue that led to it.|
Due to DNS caching there may be lingering effects on some networks, which is normal anytime any domain nameserver delegations are messed with for any domain for any reason - this is because TLD level caching at the .com level, not because the issue hasn't already been fixed several hours ago.
Unfortunately I had no warning, I did share about the disproportional impact to my users due to DNS caching to the registrar, hopefully such a issue does not re-occur. They have not given me much trouble in the past for many years of reliable service however I do not want this to happen again from them.
I also want to say thank you for several of you very proactive/responsive in observing and quickly emailing me about it, which I sincerely appreciate, even though I couldn't individually respond at that moment - it absolutely painted a very clear picture very quickly and helped get it rapidly restored and I consider your messages helpful to the process.

|Hey guys.. I hope you're having fun with all of your sites/projects! I have really enjoyed running this project, and chatting with many of you when you've had questions.|
Not a lot to report here, just thinking about you all and your cool projects, and the impact you've had on me.
I did recently re-implement the synchronization system (this is the 3rd 'from the ground up' re-design).
The last sync system (sync-v2) worked faithfully for about 7 years - it was a 'chat' system, where all slaves listened on a persistent live socket for something to happen. This was awesome for years - at the time, it spent a lot of the time waiting for something to happen. The strength was that it could immediately implement a DNS change the very second it occurred.
Over time (this year), something happened, though (a good problem, really...). More updates were happening faster then it could keep up with occasionally at brief times. I started to notice occasional periods where a lot of updates were occurring, and some of the most latency/distant slaves were falling behind. The killer was the round-trip latency. This was firing all kinds of alarms and alerts to me. Rarely did a user notice, but I did, and when I started investigating, thats what I would find.
Stability and synchronization are really important to me, and I felt like the last design was starting to get challenged by a busy pipeline.
Enter the new design (sync-v3)! Now, rather then a persistent socket / chat system, all changes are bundled together and stored in RAM, and shoved down a socket in one direction as a single bundle/blob each 5 seconds, and replayed on the slaves from a single staged journal. This is great because its no longer a round trip/chat type of implementation. Its wrapping up all of the changes into a single burst, and shoving them down the pipe at once. It took me about 2 weeks to reach the new design, and about 4 days implementing it. Isn't it funny how more time goes into thinking about things, then actually doing things? (Anyone else experience this?) I'm happy to report the transition to the new implementation seems to be working quite well!
I'd like to say thanks for your continued premium support! Still zero ads here! Aiming to continue providing a awesome real time utility for you all, inline with my beliefs on what the Internet should be like.

|The web interface was unreachable last night starting around 4AM.

ns1 is at a moved address still, its original continues to see heavy amounts of malicious traffic that is being successfully mitigated, once the malicious traffic subsides, it will be moved back.
|2012-02-17 12:19:06, 6 years ago|
|Service is restored to ns2 ns3 ns4 filtering was mitigating some of it happening for many hours through the night, now no more malicious queries are happening and levels are back to normal. I will be moving traffic back to the original IPs in the short term.|
ns1 has a hardware issue I am pretty sure, its taking some time to get it narrowed down though. The datacenter required me to format the entire server for the IRQ storm issue where the IRQ is associated with one of the 2 bonded nic's. I think its bad nic/port/cable/driver, they would not look any further until I formatted it. This happened to be at the same time as the other servers all fell under attack targeted toward some user's site - not at all related to the IRQ problem, so I thought they were blaming the attack on the previous IRQ storm issue wrongly, and that caused some confusion in our discussions.
Levels are flowing normal while this rebuild happens on ns1 which was unfortunate timing for it to have a issue of its own. I could have put that additional capacity to use yesterday/last night. It is the newest server, and I am certain would have contributed. Once things settle down here I will work on some longer term changes.
|2012-02-16 18:57:18, 6 years ago|
|Service is partially restored, I expect will be fully restored soon. ns3 and ns4 have both been moved, ns1 is currently disconnected due to provider seemingly confusing yesterday's issue with todays, the problem domain has been pulled at the TLD level, complete restoration is still ongoing.|

|One of ns1.afraid.org's network devices started experiencing a IRQ storm in what looks like a bad network card or possible driver issue.|
This curiosity was quickly discovered as it caused network flooding over 1 million packets per second and had to be disconnected from the network as to not disrupt other systems.
DNS continues to function via the other servers while ns1 is under restorative maintenance.

|I have received reports of Google seeing DNS timeouts from users as of Oct 31. |
This has been identified and fixed. The issue was queries were coming in, but responses were leaving on the wrong network, and packets were likely getting dropped within the ISP's network. Unfortunately, the monitoring system still saw the DNS traffic activity, and reported All OK.
To keep this from happening again, I have coded in some changes to the monitoring system. The health check is now sourced from a secondary IP on an external network which is forwarded to the alternate instance (instead of just a local test on each DNS server, as I had been doing prior). The effect, is to require the responses to traverse the Internet with an answer that exists only exclusively in the alternate instance, before the service can be considered OK.
Thanks for those who have reported the issue. Such a case will now raise an internal notification.

|ns3.afraid.org is receiving a memory upgrade this evening. It will return online shortly with twice the memory capacity.|
|2011-11-07 19:28:52, 6 years ago|
|Premium users have been moved to their own web forwarder today.|
I had moved the web forward system to a different provider 2 weeks ago - it seems that this provider has null routed the IP since yesterday, likely due to an attack.
I have been unable to reach them regarding this matter today. I am making adjustments to restore service to the free users this evening by rebuilding all the dns zones with some different IPs.
|2011-10-27 14:41:43, 6 years ago|

|Some code upgrades have been installed in the sync system today. The site now uses a log of journaled updates that can be replayed back from any time in history based on time, rather then tracking individual states of zones between servers.|
I believe this will improve the reliability of the sync system by allowing a server to be brought back into sync after maintenance, or network troubles more reliably. The way dns zones are built has also been re-implemented.

|ns2. will be offline while its previous configuration is restored. This process typically takes 2 to 4 hours.|
DNS will continue to function via the other DNS servers. This will restore 'Backup DNS' functionality.
|2011-10-17 09:45:40, 6 years ago|
|There has been some heavy DNS traffic today that has disrupted the flows of the service.|
I made some changes moved ns3. to a fresh IP, and initiated conversation with all network providers each server is on to see if they can enable any mitigation for the traffic flood.
NS1 CPU was exhausted - requested upstream filtering, not much luck this time
NS2 CPU was exhausted - was answering most of queries, though dropping many
NS3 Network was exhausted - high rate of packet loss at the network level
NS4 Network was exhausted - offline, null routed by provider
I decided to start building up a DNS instance with a static NSD config as an emergency solution, I had only tested it earlier this year. It took 40 minutes each time I tried to load the config - if any errors it would have to be started over. Took a bit of massaging to get it into a loadable state, but now this seems to be carrying things on NS2. I will continue work on the issue.
Update: NS4 has been restored by provider
Update: All zones have been rebuilt on the master and installed on NS2 - some zones that are not updated frequently were not installed initially.

|ns1.afraid.org has been disabled for maintenance, DNS continues to function via the other servers. ns1.afraid.org appears to have reached a OS memory limit, and started rejecting some updates to certain zones.|
In response to this, and also considering many zones are not valid that users have added, I am reducing the number of zones that must be loaded by disabling zones which have not passed the domain delegation health check a single time in the last 1 year.
This may be further reduced to a period of 90 consecutive days in the future, which is probably more reasonable.

|A user of afraid.org had a domain that around 7:30 AM PST came under attack, with many gigabits of malicious traffic at its peak directed to all afraid.org DNS servers. The attack is still in progress at the time of this writing, but has been reduced significantly.|
While attacks are not that unusual for afraid.org, they are generally not this large as today.
Unfortunately - this exhausted every ounce of resource available for afraid.org, and caused serious disruption for the site afraid.org, and for innocent bystanders sites that are also using afraid.org for their own sites.
So, after today's eventful morning, I will be taking further measures to protect users by increasing the available nameserver pool size from 4, to at minimum 64, and begin allocating configurations to members in a way that minimizes overlapping configurations as much as possible.
Over time I have observed that much of the human based problematic events such as this one comes from (a relatively small set of) unpaid members, it is a sad truth. I will not stop providing the free portion of the service, but I am strongly leaning toward moving paid members to their own tier of servers.
While afraid.org has not had a problem of this kind in a while, I'm going to reflect on this event and take measures to make the site better because of it.

|There was an interruption in DNS this AM, unexpected traffic levels were the cause.|
It appears a member of the site's domain came under heavy attack, and a malicious individual decided to attack the DNS servers, rather then the site its self.

|2009-03-18 01:41:54, 9 years ago|
|The disk issue that is happening is that the primary disk is reporting more available space, then what could be possible.|
This could be an indicator of possible file system corruption, though there does not seem to be any operational problems aside from an inaccurate reading of available disk space. There are no SMART errors being reported.
This event was reported nearly immediately via health monitoring checks.
Worst case scenario, is re-installation of the operating system, and possible disk replacement.

|The nightly backup system at 1:29AM PST each night for 10 to 20 minutes would cause a severe performance hit to the site, (yet perform a very important task).|
This method of backing up the site's database has been abandoned in favor of live offsite database replication.
The site will no longer have this routine interruption, as the slave server will always synced up any given moment to the second.
The international users of this service may especially appreciate this change. Though backups were performed early in the morning in the US, it is always peak time somewhere.
|2008-04-20 14:43:47, 10 years ago|
|A locking issue with the zone syncing system has been fixed.|
This issue was responsible for many "reload queue is full" error messages in the event of any one of the slave servers was running slow, or held up during a server reconfig which can take a few minutes.
The queue performance now shouldn't be impacted in any way whatsoever by the state of slave servers, (unlike before).
A future change / note to self might be to offload the queue to something that does not have such limited capacity and use message queues for event notification only. However right now if the queue is full (indicating > 30 users changes are pending) there is probably something going on that having a bigger queue won't fix given today's change, so we'll see how this does.

|A few hundred accounts got banned this morning unintentionally, they are unbanned now.|
My provider had started proxying my HTTP traffic due to an attack, and anyone who had any activity to their account started coming from the same IPs, which was triggering the ban system. I'll be whitelisting their IP space, as soon as they tell me their range.
I turned off the webserver until I could write a script to repair the database and clean out the ban triggers that had spread like wildfire to limit the damage.

|Most domains have fallen into a broken state for reasons that are not entirely known yet.|
The tool used to check domain authority stopped working, and also does not work from different servers, this indicates no one is blocking afraid.org's nightly bulk checks.
I'll see what I can figure out / find out about it.

|The primary server (web interface) had gone unresponsive around 5:30 AM CST from what I could gather through my providers traffic statistics.|
I put in a reboot request at 8 AM, once discovered, all daemons were running by 9:30 AM CST or so. The cause of the problem is yet to be determined.

|For users of the 'web forward' section:|
At approx 7AM PST the URL redirection IP was blackholed by my upstream provider, due to a network attack against afraid.org.
10 hours later (5PM PST) it is still blocked after my attempts over the last 2 hours to get it removed.
I'm going to force the URL redirection IP to be changed, this requires all zones to be re-generated, and re-loaded into the DNS software, this can take a bit to do. They should all be up shortly, one way or another.
Given today's incident and duration, it is clear this is not an adequate structure for the URL redirection.
Changing the IP of every URL redirect system wide on a moment's notice for everyone presents some challenges. The use of CNAMEs instead of A records as web forward destinations would be ideal. CNAMEs however, can cause conflicts with other record types in the same glue path (such as NS records) of which A records do not. I may begin using a combination of both.
I will continue to think on this problem, and see if I can work on a solution that will utilize all DNS servers for web forwarding in addition to just DNS and web interface access.
As with most of the inbound attacks, I generally don't get to know who, what, or why they occur. It very likely has nothing to do with me. I can only suspect someone upset someone else, and I got the cross-fire.
I will post a follow-up to this post. But that's today's news.

|Users may be able to notice an increased responsiveness to the website, and performance during the last couple of days.|
The average CPU load for the primary afraid.org server has been reduced to 30 to 40% of what it was.
Statistical analysis of traffic is being moved to a non-production server all together.
This is after 2 complete rewrites of this portion had been done in the past to accommodate ever increasing traffic.

|Every once in a while, dynamic dns updates stop happening to a single zone.|
Users sometimes notice this and contact me, letting me know they have been waiting X hours for their IP change to show up.
When I hear about such a thing, I would often go through the logs, and see there are errors which the DNS server software is rejecting. I would then (by hand) go to the zone and find the line number, then go find the record in the database that causes the conflict, and remove it and force the zone to be re-generated.
Today a new daemon has been built which watches for any such errors automatically, and sends both me and the creator of the mal-formed record an email informing us both that any conflicting record has automatically been removed.
This will not only keep a zone functioning if somehow a malformed record makes it through the web interface, but also send me helpful diagnostic information to build a tighter system of error checking.
This was somewhat of a rare problem, but when it would happen to a zone like mooo.com which over 30,000 subdomains use, it has widespread affect on members who are unable to update their IP. This should now no longer be possible.
This sort of a setup is also going to be especially useful when allowing support for new record types.

|MySQL has been upgraded from 5.0.37 to 5.0.45 tonight in response to some undesired behavior. Upgrade fixed it.|
|2007-04-24 06:34:51, 10 years ago|
|All servers were upgraded to the latest stable version of BIND 9.4.0 last week from 9.3.4.|
In the process, the query stats output has changed slightly (for the better). This change has been throwing my numbers (queries per second and DNS stats page) off for the last week, as it was not reading all the counters.
I've updated the stats scripts to accurately read the new values they added, and am re-parsing all of the old stats dumps, to repair the DNS stats section with accurate data for the past week.

|Nameservers now are no longer instantly reconfigured upon domain addition. This should have a substantial impact on the previous DNS timeout problem that would occur randomly throughout each day.|
While I much like the idea of providing instant zone additions, the reachability of the DNS servers is most paramount.
This should not impact IP changes/adds/updates, they will continue to occur in the order in which they are received (real time or near real time).
When a new zone/domain is added, a configuration reconfig must take place on the nameservers before a new zone can be served up. This process causes a nameserver to become unreachable for a short period of time while it analyzes its configuration for change.
This is still true, I cannot change how the DNS server its self is designed (though I understand much work is going into a threaded model that can answer queries while simultaneously updating its configuration, so I doubt this will be true forever).
As for now, this is a problem that has only increased with the growth of zones hosted. The problem translated into all sites receiving a DNS timeout when all nameservers do this at the same time. The problem was somewhat short, and random, but I'm sure several have noticed it, I know I have.
The add/delete a domain pages have been tuned for higher performance in the process of things, and the 'execute queue' button has been removed.
The domain additions/deletions should be fully propagated to all servers within 5 minutes at any given moment. Each nameserver will reload their configurations on their own staggered 5 minute interval (but never simultaneously, via a shared network lock, thereby preventing a total mini-blackout randomly throughout the day).
|2007-04-17 23:50:24, 11 years ago|
|The add a domain page has been tuned a bit.|
After some analysis and benchmarking, it was found that the domain namespace collision detection code specifically was the culprit for some unnecessary slowdown.
For example, this is the code that would prevent 'test.mooo.com' from being added as a domain, when mooo.com is already an existing domain, and vice versa.
Incase anyone might be interested, domains are now stored indexed in reverse, and each section of a domain 'com', 'mooo.com', 'test.mooo.com' is searched for as exact match, then searched on with a wildcard character.
Storing and searching for collisions in reverse (Example: 'moc.ooom.tset.*' vs '*.test.mooo.com') allows a great leverage of the database indexing capability, since domains/subdomains depth grows from the front.
Before this change, it was loading the entire list into an array, and performing a regular expression search inside of the application, for each and every time someone added a domain. There was a point in time where that was not a impactful method. Today I noticed a 100 MB httpd process and seen it was executing a domain addition, and that led to today's rewrite.

|The last day or two there has been an issue which surfaced. The DNS server software has grown in RAM consumption to manage to hit a single process RAM limit in the OS. The FreeBSD default per-process limit of 512MB has been bumped up to 1GB.|
Since raising this value, things seem to be performing better.
|2007-04-11 19:27:54, 11 years ago|
|Database server has been upgraded to the latest stable version.|
The site was disabled during the back-up process, prior to installing MySQL 5.0.37 from 4.0.20.
An attempt was made to do an initial sync off the live binary files to minimize downtime, however that seemed to load the server down to the point of being unresponsive anyways, so it made sense to shut down the web and database server all together, which made it go about 10x quicker.

|Latest OS/kernel snapshot is now running live on the primary server.|
|2007-01-31 10:51:46, 11 years ago|
|Hardware or OS?|
After the incident this morning (woke up to a load average of 200+), I am having thoughts about the issues with the server not necessarily being hardware related.
During the nightly backup (around 01:30 PST) the server ran out of disk space, however it was not showing it was out, which is *very* unusual, it was as if something in the OS was hanging it up.
The server is going to be brought down again to re-update the OS and kernel on it. We'll roll with that and see how it does. Its in the process of compiling the latest snapshot.
There is good news though, the ISP has recently agreed to do a chassis swap on the server just incase it is a actual hardware issue. I'm going to delay this route for now though, and see if a rebuild of the OS/kernel fixes these issues.
With these changes, this issue should be isolated soon.
|2007-01-23 03:06:29, 11 years ago|
|The diagnostics have been completed, nothing interesting was found.|
Still trying to sort the issue.
|2007-01-20 11:34:58, 11 years ago|
I have scheduled the diagnostics run, the site/server will be taken down beginning January 23rd 2007, (Tuesday morning) @ 1 AM CST for diagnostics by the server provider to attempt to locate the source of the crashing thats been happening every 2 weeks or so.
The expected downtime is roughly 4 hours.
|2007-01-01 09:48:12, 11 years ago|
I've been having some crashing issues with the server. (about once or twice a month). Going on for 3 months or so. Previous server never crashed, and it was much less powerful. I can't seem to re-create or induce it (but I also don't want to take the site down trying to break it either).
I'm working with the provider to try and get it resolved/diagnosed.
A simple reboot of the server takes about 1 hour to get all daemons and processes operating correctly at minimum.
It was taken down a few moments ago to setup some remote console/DRAC up on it to see if there are any further indications of the cause there.
Sometime in the future it will need to be taken down for some extensive tests, when this happens it will be done during the night time in the US which is the least busy time.
I've been trying to get a loaner server to minimize the outage/problems while this is figured out, but the provider is convinced its not a hardware issue currently, and I can't prove it otherwise, since no interesting log messages are written to the disk.
All the best... happy new year everybody.

|2 nights in a row the primary server has crashed.|
The hard disk is almost full, I'm going to try and free up some space, and move the databases to the 2nd SCSI disk.
It happened both nights at about the same time, during the nightly backup.
Even with a full disk, things shouldn't go down though.

|New server has been ordered!|
Should be ready to go within the next week or two.
This will be replacing the current one, and therefore will be issued some new IP space, which should only impact those using DNS branding, whom I will email.
OLD] P4-3.2 GHz HT / 2 GB / 80 GB IDE hard disk
NEW] Dual Xeon 2.8 GHz / 2 GB / 2-SCSI 10k RPM drives
This should result in a web interface performance boost, now that I'll be able to offload some slow statistical analysis programs onto a 2nd hard disk (and SCSI to boot!).
Though it has a slower clock speed, it is a dual with larger caches, so the processing power will be signifigantly increased.
I'm also in the process of re-designing the nightly backup system which is the cause for about ~1 hour of more-then-necessary sluggish web interface performance that I've been getting a taste of first hand (oddly enough no one else has really mentioned noticing).

|Account hostname limit behavior has been changed a bit.|
Due to abandoning the live NS authority check upon a domain addition, this opened up the ability for people to gain unlimited hostnames in their account by adding non-existent domains into their accounts.
As a result, the system has been changed to still allow 20 hostnames per domain, but the 20 hostnames are restricted to each individual domain. The 5 'free for all' hostnames can be used on existing domains, OR via the shared system.

|2004-12-31 17:34:24, 13 years ago|
|Backend system has been rewritten.|
Configuration changes are handled much more intellgently now, this will reduce load on the server, and increase response time.
This also allows users to mass-add domains without creating undo stress on the server with the new ability to load changes into the nameserver when they're done.
Those who don't use CNAME's and do mass dynamic updates are also reduced/consolidated, the queueing system is shared, so if 2 people add domains at the same time, and 1 executes the queue, the other person when they execute the queue will not do the same redundant task.

|For anyone having trouble recently with CNAME's not resolving, this problem has been fixed.|
Due to the transition phase of moving to the new ISP, their temporary server ran out of inodes on /, which required me to move all DNS data to another partition on the server with more room.

Have sync'd databases over from the temporary loaner server my new ISP, National Net, was generous enough to loan to me to avoid downtime.
Load average is much lower, and server is much more responsive. DNS queries per second has also increased, normally around 120 has been doing between 300 or 500 since the switch, which... I had not expected. Inbound throughput is the same, but outbound is quite a bit higher with the increased queries per second, which I can only attribute to the increased CPU power.

|Speaking of reading the webserver logs... there is a awful lot of dynamic DNS updates being issued to the server, let me just say a couple things.|
1) If you have 8 hostnames, you don't have to update 8 hosts. All you need to do, is update 1 host, and make all the other hosts you want to be updated CNAME records to the hostname you are updateing. Also keep in mind, you can use CNAME's with any hostname on the Internet, so if you have multiple dynamic dns accounts with other providers, and you are updating your IP there, you don't even have to make updates to freedns, you can make all your hostnames CNAME's to that host.
2) Some people are writing their own update scripts and running them once a minute, not only that but doing it for multiple hosts and updating each host. If you download and install php from www.php.net as a command line tool (./configure && make && make install), you may find this script useful. You are free to write your own, but that checks if your IP has changed every 5 seconds, and makes a single update to the server only when the IP changes.
I would appreciate updates not being made once a minute, but instead only making updates when necessary ideally. It's not really a problem right now, but I don't ever want it to be either :)

|Added mod_gzip to freedns.afraid.org today, so now the 'add/edit a subdomain page' should load faster, I was noticing my logs saying that page was 110k, and it just seemed sluggish overall, and is one of the most regularly accessed pages.|
After installing mod_gzip it shows up at about 26k in the logs now, and seems to load faster from here. ASCII text compresses very well, the domain registry page which was about 1.2 MB in size comes down the wire using about 78 KB of bandwidth, which on my home connection loads signifigantly faster, so instead of having it broken up over multiple pages I have made it 1 large list again, which makes it easy to find a domain by using CTRL+F, instead of searching through the drop down box.
|2003-04-22 19:43:05, 15 years ago|
My ISP only charged me for bandwidth at cost, which was $470 last month, things could have been much worse. They gave me a break from what I would have owed according to my contract with them.
Hopefully I will have a more long term anti-ddos setup in place in the near future, when my ISP allows their customers to block their own IPs it should be pretty sweet.
|2003-04-15 11:44:18, 15 years ago|
$3200 worth of bandwidth, in a day.

|Afraid.org was down due to a power supply failure.

I'm 2000 miles away, so I had to hire them to fix it, they were very speedy in getting it back up once they received the signed work order, glad to report things appear to be back and running ok. Sorry for the outage, but glad it was an easy fix ($125/hr).

|FreeBSD OS upgraded from 4.2 to the latest 4.7 today. I was dreading doing this remotely since I do not have remote serial console access to the server should something go wrong, but I wanted to do traffic shaping which required a new kernel. I am pleased to say the upgrade went extremely smooth with no problems! :) My last FreeBSD 4.2 installation was over a year old.|
In light of the recent DDoS attacks I wanted the ability to limit how much data could reach actual services, in one of the recent attacks that I did not publish, the load average went through the roof on the server (40+), and lag was so bad that I could not even see what IP was getting attacked, or what "run away" program was bringing the system to a grinding halt. Now with traffic shaping installed, the kernel will drop excessive traffic and not even try to have any applications process it.

|Another DDoS happened just now...|
Only 8 hours from the last one.
The night crew at my ISP seems to be faster to respond. I pay for bandwidth on the 95th percentile, so it would take 36 hours of flooding (combined throughout the month) to effect my bandwidth cost.

|Another DDoS today...|
Seems to be a regular thing now. Good news is they're getting easier to stop.
Service should have been mostly uneffected.

|Yet another DDoS attack, just a few moments ago. I phoned my ISP and asked them to block the old IP ns1.afraid.org was on, the attack however was also aimed at ns2.afraid.org.|
ns3.afraid.org and ns4.afraid.org aren't being attacked, which makes me think instead of an IRC user, someone is trying to get someone's domain shut down within freedns? Perhaps someone who hasn't updated their domain with ns3.afraid.org and ns4.afraid.org records has ticked someone off using their domain hosted in freedns. This time however afraid.org has had no down time.
I'm ready for IPv6 to come out... this is so lame... I wonder if the attacker is reading this... the type of attack is a distributed attack, from maybe hundreds of zombie computers that the attacker has control over. When the attack bots are instructed to they will flood a network link with garbage traffic. The problem, is many ISP's on the Internet don't have their routers configured to stop IP spoofing from their networks, on these particular ISP's a user can send traffic out without using a real IP address for the return packet, and their router passes it to the public internet.
If ISP's made sure users couldn't spoof from fake networks these type of attacks would be easy to track down. IPv6 should fix this by default. It could be fixed with IPv4 but due to clueless admins being able to attach their networks to the public Internet, not much can be done from my side. My best defense is moving public dns traffic to another IP address.

|Another DDoS today. I phoned my ISP and asked them to block ns1.afraid.org from the Internet. Static FreeDNS IP users should have been uneffected however those with dynamic addresses were unable to make updates for about 6 hours. The server was blocked within 15 minutes of the attack. I was told it would automatically be unblocked after a period of time, but it wasn't, I apologize for the lengthy outage, when I phoned in a 2nd time they had me unblocked within 15 minutes.|
Also today an ns4.afraid.org has been brought online, thanks to Ben Kerensa for offering to supply the server and bandwidth for this. I would like to encourage everyone to update their domains to support ns3.afraid.org and ns4.afraid.org which have both recently been brought online. ns3.afraid.org which has been operational for a few weeks now is generously being hosted by Donald Williams.
Since DDoS attacks seem to not be stopping (and I am assuming the source of this attack isn't even a FreeDNS user but maybe a direct result of someone trying to attack another freedns user and thinking I am an ISP) I am looking for ways to keep the website up through an attack. I'm going to move public services to another host and see if the attacks follow it. I'm also considering setting up pass through cache servers to protect the real server, but I have to determine if this attack is aimed directly at me or not, time will tell.

|4 day ns1.afraid.org outage, and 330 day all time high uptime lost...|
Well ns1.afraid.org was packeted with 700 megabit of traffic this last weekend, which resulted in my IP and subnet being blocked off in multiple places by my ISP and one of their ISP's, the attack was large enough for them to notice, it basically took 4 days, multiple telephone calls, and multiple emails to un-block ns1.afraid.org from the Internet because no one could login to my server from the console to find out why it still wasn't online even after they thought they un-blocked me in their routers, I guess my keyboard port on ns1.afraid.org no longer works according to the tech, so that made it incresingly difficult to resolve the situation, and ns1.afraid.org almost got de-racked and looked at by a hardware tech. Fortunately they found the additional null routes in their routers and I can get to my server once again.
This is the first time I have had to rely on ns2.afraid.org to actually carry the load of the DNS traffic, initially ns2.afraid.org was mis-configured, and with Allen's help at spysatcentral.net who is hosting ns2.afraid.org I was able to get it functioning to serve DNS with the last transferred zone files from ns1.afraid.org while ns1.afraid.org was unreachable for the last few days.
What I have really been wondering, is Why on earth would someone packet this server? Who did I upset? Due to the way the Internet works (a public network we all share) it is impossible to block these types of attacks when they originate from comprimised machines from all over the Internet. Fortunately though the worst that packeting can do to a system is make a system unreachable for a period of time, but with the communication issues I had with my ISP, the downtime was a bit longer the I hoped for. I don't know if the attack was directed at me, or directed at someone who was using an afraid.org hostname. DNS traffic on afraid.org consumes a (comparitively) very small amount of traffic, and could get by with having the server on a cable modem but it wouldn't be as responsive to dns requests, and subject to outages much more regularly, I chose to put the server in a nice 100 megabit burstable facility instead, for better response times and rock solid power protection.
Well thats all the news I have, sorry for the outage, it was totally out of the blue but I can't stop my ISP from turning me off when my server uses a volume bandwidth they don't expect me to pay for. At least I didn't get stuck with a huge bandwidth bill like some other ISP's would probably try to do. The folks at he.net are great.

|Sponsor count is updated immediately now on the site. I have been incrementing/deincrementing the sponsor count by hand up until now, there have been 82 subscriptions to FreeDNS and 29 cancelations to net 53 current subscribers I had 56 in there so my count had gotten off somehow.|
The moment someone makes a subscription the sponsor count should immediately update. Same goes for if someone cancels the donation subscription.
Thank you subscribers for doing what you can to keep the service alive. Last month FreeDNS's combined donation income was $146! I am very pleased to say FreeDNS is getting close to having it's financial goals met. Great work guys!

|For those of you who don't follow the forums area in FreeDNS there has been a few recent changes to the service|
* Multiple MX support - You can now set your MX to something like host1.afraid.org,host2.afraid.org (no spaces) and priority on the MX will be set in the order you enter the hosts, if you don't know what this means it probably doesn't effect you.
* Shortened TTL - Your ISP's cache should drop any old entries you used to use in FreeDNS within 60 seconds of your address change to a record in FreeDNS.
* Pending status removed - If you add a domain, it will instantly be accepted into the system and fully functional
|2002-10-15 21:28:49, 15 years ago|
From 12 noon to 9:00 pm PST it looks like afraid.org's was unreachable to the Internet due to my provider being down, things seem to be operating correctly now.
|2002-04-16 01:36:13, 16 years ago|
|Fixed a bug that was causing certain domains not to update do to mal-formed mutilated records in the zones breaking all records within a zone.|
|2002-03-09 22:56:56, 16 years ago|
|Made secondary DNS and dynamic DNS areas live and visible to all.|
|2002-03-06 20:04:51, 16 years ago|
|Added IPv6 (AAAA) support|
|2002-03-01 21:35:20, 16 years ago|
|MySQL upgraded to 3.23.49, site was down for about 30 mins for the upgrade.|
|2002-02-28 21:42:19, 16 years ago|
|PHP upgraded to 4.1.2 on the server as per the advisory at security.e-matters.de. Upgrade had no problems.|

|Many of the accounts in FreeDNS are not regularly logged into. In the last day, there have only been 32 users who have logged in, and of these 32 users, 2 have made a contribution. Thanks to these 2 users, 7% of the hosting costs for FreeDNS have already been eliminated, I hope this encourages those who have not donated yet. If you find this service useful, please make a contribution. There is great power in numbers that choose to stand together!|

|I was doing some reading tonight and found out that for me to become a REGISTRAR to allow domain registrations in FreeDNS it would cost $2,500 USD for the application and $4,000 USD a year, and an additional $500 per TLD per year. It's too bad that I can't afford to do this because I would really like to. If they don't slap on an additional fee per domain registration, and I could get the financial backing to do this by anyone, I would be willing to give away free domain names. If anyone is interested in funding this project, let me know!|
|2002-02-22 11:31:02, 16 years ago|
|I've updated the Sign-Up FAQ (Not linked inside the members area) that some of you may also find useful, it also tells a little bit about Afraid.org and it's background Click Here|
|2002-02-22 03:24:58, 16 years ago|
|The problem with subdomains with periods in them not being able to be NS or CNAME or have MX records has been identified and fixed. NS records take all authority for a subdomain so instead of leaving this feature disabled, a check has been put in place so conflicts no longer happen and service can continue as normal.|
|2002-02-22 03:07:52, 16 years ago|
|A new feature has been added by request of a user, the feature can be found for domain owners, if you click on Edit SOA you'll notice an AXFR checkbox, if that is checked (off by default) hosts anywhere on the Internet can transfer your entire zone file and all the hosts in it to their systems.|
|2002-02-22 02:53:36, 16 years ago|
|I'm pleased to say that the load average on afraid.org is at an all time low. I'm sure many of you have noticed a signifigant speed increase with the new FreeDNS interface.|
If any of you have any ideas for a feature that you would like to see in FreeDNS let me know.
|2002-02-20 17:16:19, 16 years ago|
|New version of FreeDNS made live!|
Lots of changes and security fixes, I would like to hear any comments/suggestions about the new layout that you might have, feel free to contact me.

|NS2.AFRAID.ORG is now properly working!|
Somehow the IP address for NS2.AFRAID.ORG got switched at the registrar and when I tried to move it back the secondary nameserver that has been donated to afraid.org had already been setup as a nameserver for another domain so NS2.AFRAID.ORG is now on it's own IP address on that server hosted at a totally seperate place then NS1.AFRAID.ORG (they're 1800 miles apart).
|2002-02-06 11:50:38, 16 years ago|
|Added support for Secondary DNS!|
Users may now add their domains into the secondary DNS section for JUST secondary DNS hosting.
|2002-02-04 05:03:45, 16 years ago|

Users may now update their IP address to their current IP address by fetching a single URL. Useful to put into a re-connect script.
|2002-02-04 05:02:31, 16 years ago|
|Added URL Redirecting!|
Users may now redirect any subdomain.domain.com to any URL of their choice.
|2002-02-04 00:43:35, 16 years ago|
|Added support for Round Robin DNS!|
Users may create multiple records with the same hostname to take advantage of this feature.
