Re: Cogent/Level 3 depeering

Since Cogent was depeered couple times before and each time they fairly
quickly setup transit connection (without statement like the one below),
I seem to be getting an impression that they are a lot more angry this
time for whatever reason and it might not be resolved quite as easily.

Am I wrong to think that this is not quite the game of chicken this time and neither one will provide connection to the other unless a lot and lot of outside pressure is put on them to resolve it?

This is what I just got from Cogent support. I'm still waiting on the billing dispute ticket. I've already told our payables department to not pay any Cogent invoices, this should get fun. Hell, I wish Verio never sold me to Cogent in the first place, it is all their fault :/


As of 5:30 am EDT, October 5th, Level(3) terminated peering with Cogent without cause (as permitted under its peering agreement with Cogent) even though both Cogent and Level(3) remained in full compliance with the previously existing interconnection agreement. Cogent has left the peering circuits open in the hope that Level(3) will change its mind and allow traffic to be exchanged between our networks. We are extending a special offering to single homed Level 3 customers.

Cogent will offer any Level 3 customer, who is single homed to the Level 3 network on the date of this notice, one year of full Internet transit free of charge at the same bandwidth currently being supplied by Level 3. Cogent will provide this connectivity in over 1,000 locations throughout North America and Europe.

For status updates and further information on the special offering -- please see our status page at

have 2 other providers so I can still reach Level 3.

We tried the same line with Level3 - and were told "Tough, we're not paying
service credit. The transit still works, just its coverage is slightly

Maybe I can buy the new 'Cogent - it is almost the Internet' service
for less money.
Indeed, that's the natural next step.
