Cogent De-Peering - 03-18-2008, 01:18 AM

This is being posted for informational purposes only and does not affect our servers, or your ISP's connection to our servers at all.

Anyone with certain ISP's may have problems accessing certain parts of the Internet. This wont affect any of our servers because we do not use Cogent, and therefore we still have 100% connectivity to the world. The Sacramento network DID use Cogent but we are not there any longer since a few weeks ago.

What it will affect is your ability to view parts of the Internet if your ISP uses Cogent as their bandwidth provider, or if you have websites on other provider servers besides us that use Cogent. Many large ISP's and overselling hosting servers do use Cogent because the price of bandwidth is significantly less than everyone else.

This from Telia to their customers:

Quote:
Dear Customer,
We would like to give you the following information:
Cogent has decided not to exchange traffic directly with TeliaSonera’s AS 1299 or indirectly with AS 1299 through a third-party provider. As a result, Cogent has partitioned the Internet and disrupted the flow of traffic between Cogent and TeliaSonera customers.
While this has a negative impact on some users of the Internet, this effect is the result of Cogent’s decision and is unfortunately beyond TeliaSonera’s control. Until Cogent rectifies this situation, TeliaSonera customers experiencing any difficulty reaching Cogent’s network can continue to purchase IP Transit from TeliaSonera along with another Tier 1 provider. This will fix the immediate problem and ensure optimal connectivity going forward.

We sincerely apologise for the inconvenience caused…

If you have further concerns, please address your commercial contact at TeliaSonera
This is yet another instance of Cogentco's ongoing peering wars destroying the Internet.
