They are at PAIX. The last I contacted them they had a "very open policy
about public peering". Try contacting <peering@cogentco.com>....they
respond in my experience.

My impression is that their connectivity is primarily provided by one or
more transit providers (I know only of above.net) plus a bit of peering.
I'd imagine their links to their transit providers would feel the pain
first. I'd expect that they'd notice and upgrade the links just as
everybody else does. It would move on up the chain. Of course, if most of
the traffic were sourced/destined for a particular spot either Cogent or
one of their transit providers would increase peering. If it was just a
popular bit of content (Web site, RealMedia stream, whatever) that one of
their clients was hosting and that amount of traffic was being pushed
I'd imagine a lot of people would want to turn up (or upgrade existing)
private peering links with them. Problem resolved. I doubt anybody would
feel much pain other than perhaps Cogent and their end-user for a finite
period where the upgrading would be going on.
Perhaps I'm optimistic. YMMV.
