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 stopped peering and if somebody has questions they should call 
AOL to complain .. (with phone# to their NOC provided in the letter 
- not very nice thing to do it like this in my opinion).

If nothing else, Cogent could be using their idle 6461 transit, instead of 
grandstanding by overloading their Level 3 capacity so they can blame AOL.

is it really idle ?

Why wouldn't Cogent create a community string to provide its multihomed 
customers with prepend 16631 (or customer asn) to Level3 peering sessions
to control inbounds better?

Because they do not do custom anything.
