AOL (AS1668) stopped peering with cogent yesterday for reasons they did not disclose publicly. Cogent sends same letter to all customers who asked for what is going on and in the letter they say that two weeks ago, peering to AOL was upgraded to OC48 from OC12 and now for some reason AOL

Me thinks Cogent doesn't have a problem with congestion on the inbound direction. Fix your reverse path. Customers of Cogent should be/are more concerned about congestion on the inbounds at Level3 - Cogent; outbound is way too easy to control. Cogent has a pile of available inbound -

Of course, your right about what needs to be fixed! But situation with cogent is such that I do not have that option. Their peering link with level3 is congested because of all the traffic going to AOL and some of traffic destined to me is going through same link the other way and
