Sprint Cuts Cogent Off the Internet
superbus1929 writes "I work as a security analyst at an internet security company. While troubleshooting an issue, we learned why our customer couldn't keep his site-to-site VPN going from any location that uses Sprint as its ISP: Sprint has decided not to route traffic to Cogent due to litigation. This has a chilling effect; already, this person I worked with cannot communicate between a few sites of his, and since Sprint is stopping the connections cold (my traceroutes showed as complete, and not as timing out), it means that there is no backup plan; anyone going to Cogent from a Sprint ISP is crap out of luck."
Well, for Cogent this seems to be a standard practise, so I'd say not enough...
Internet Health Report
Cogent is the one behind the story in link and it's obviously one-sided. Most of the time, ISPs get de-peered because they deserve it. However, the smaller ISP almost always gets away with it because they play the part of the victim who got severed and they usually win on the PR front. Pressure mounts and the larger ISP eventually settles and re-establishes the connection despite getting the raw end of the deal.
What generally happens is that these tier 1 ISPs start off with equal amount of traffic that is being routed on behalf of the other ISP so they're both giving each other equal value. But that balance shifts over the years and you might have one ISP giving back 1/8th of what they're taking but the larger ISP is afraid of bad PR if they sever the connection. What might be needed is some sort of arbitrator who will look in to the facts without blaming one side or the other and just examine the facts and issue a recommendation. During that period of arbitration, the peering should continue so that customers aren't affected. If one ISP is found to be unworthy of a settlement peering arrangement because they're not holding up their end of the bargain, then they should be ordered to pay. If they refuse to pay, they deserve the blame for not paying for their Internet backbone.
Plenty of ISPs pay for their peering arrangements if they're not able to build some backbones of equal value. There's no reason some ISPs should get a settlement free peering if they're not willing to upgrade the Internet's backbone infrastructure.
Oh, right, sorry about that. Put "public" in for both the username and password.

AOL repeered with Cogent something like a year ago. They were the last holdout and once that happened, Cogent was no longer paying anyone for transit and were therefore a full tier-1. Regardless of their peering status, they own and operate the second largest capacity network in the world. Traceroutes over the last couple of years would seem to indicate that they are servicing a fairly large number of eyeball networks in Europe these days as well as content networks all over the world. They are now sitting at the grownup's table and are no longer just a "discount" provider.
Nothing worthwhile ever happens before noon
What happens when Cogent gets bored with Sprint and gets bitchy with your new choice? This is not the first time Cogent has been in the same situation. Level3, TeliaSonera, and AOL come to mind. I wouldn't be so quick to blame Sprint based on a one-sided Cogent press release.
this is my sig
In 2006, Sprint and Cogent entered into a commercial trial agreement. Cogent failed to satisfy Sprint's peering criteria and refused to pay Sprint to stay connected to our network. Sprint notified Cogent well in advance that it would disconnect Cogent unless it paid, and Cogent refused. As a result of Cogent's refusal, Sprint was forced to terminate the commercial interconnection agreement and disconnect its network from Cogent's. Cogent's posturing is nothing more than an effort to divert attention away from its' contractual obligations, and this is the latest in a growing list of peering-related disputes between Cogent and Internet backbone providers.
