Cogent's mess also took down Wikipedia 

I've been poking around on the Internet and have noticed that there are many hosting providers who've been affected by the Cogent mess. As such, there are some high profile sites that were affected by the disaster.

One of those sites is Wikipedia, the popular, free online encyclopedia. Wikipedia was down for over two hours, according to CNet News.

I've got a feeling they'll be lawsuits coming over this trainwreck.

With the hosting companies, having to credit their disgruntled customers for not being able to meet their "99.9 percent uptime guarantee", the costs for Friday's Cogent fiasco will quickly add up!

Clients who rely upon their websites for sales, will likely seek reimbursement for lost revenue.

There is a saying in the business world: Time is money. In the world of Internet web hosting, downtime is lost money.

This could get very nasty!

Update from concerning outages 

12:33 08/19/06 Update: We are asking that all affected customers please be patient while the new IP addresses resolve. The new IP's were put in place on all affected servers from 11 PM to 4 AM this morning. Server side DNS propagations take 12-24 hours. We also had to change name server IP addresses which need to be updated at the ROOT DNS servers. This could take up to 72 hours. During this time your email will not be lost. If email messages are trying to be sent to your server they will remain in the sending queue until either the server sees the new IP address or the TTL expires, in which the sender will be notified and can try to send again. Any messages already on the server will not be lost. You will be able to download them. You can get to your website and email sooner by manually assigning your primary name server as your default name server on your NIC within your PC. To do this, right click on your "network neighborhood" and click on "properties". You will then see your listed connections. Right click on your cable/DSL connection, then select "properties". When the window opens, scroll down to where it says "TCP/IP" and select properties. Put a dot where it says "use the following DNS server addresses". Then put your primary name server address as the preferred name server. You can leave the alternate name server blank. This issue started from a "disagreement" between Cogent Co and a peer point located in D.C.. Cogent Co thought it would be best NOT to replace a failed router and decided to allow a wealth of hosts such as, suffer due to the loss of IP space.

Cogent connectivity issues cause outage 

All of my sites were down for most of the day Friday, due to trouble on the 207 network at Cogent. Cogent is the company that provides the bandwidth for the servers which host the following three websites:

The sites that were effected have an IP address beginning with "207". This included all of the sites above. Below is the updates that were posted on the admin board at the hosting company.

The hosting company finally fixed the problem by switching us to the 208 network. It is unclear, at this time, whether that move will be temporary.

Also, my mail server is also on the 207 network, so it was also inaccessible throughout most of the day on Friday. If you sent me, Jackie Patru, Chris Gerner, or anyone else with one of the above domain names in the e-mail address, you may have to resend.

13:57 - Our upstream provider for the datacenter in which your server is hosted experienced a temporary Network connection loss during emergency maintenance on their network. Your server is actually up and running now. Please note that we were not given any ETA, so additional downtime may occur. Please be patient while their engineers fix the issue at hand.

15:53 - Update: The network issues should be resolved by 17:30 at the latest, but network administrators are hoping for a resolution sooner than that. The entire 207 network provided by Cogent is affected. We truly apologize for the inconvenience.

17:36 - Update: Engineers are still working on the 207 network, and will resolve the issue as soon as possible. We apologize for the inconvenience.

17:52 - Update: Engineers have fixed most of the network connectivity issues.

20:57 - Update: Engineers are still fixing a few lingering issues, but for the most part,'s 207 network access has been restored. Because of the lingering issues, some clients may still not be able to connect to their websites and email.

22:35 - Update: We are changing out IP addresses to 208.* on the affected servers for clients who still cannot reach their servers due to Cogent's network issues. We will leave the 207 IP's in place for redundancy until the new IP addresses take affect within 12-24 hours.
