So it does look like Cogent bent somwhat...I'm guessing they agreed  to
pay some sort of "traffic imbalance fee"?

There are other possibilities.

Maybe they agreed to pay a transit fee should they fail to carry the L3
user's requested traffic as far as possible before handing it off (cold
potato routing) and hand it off at the earliest possibility (hot potato
routing) leaving L3 to backhaul it across the L3 network to the user who
requested the data.

I doubt it. Cold potato is normally the first thing Cogent offers in a
situation like this. I'm guessing this went something beyond that. Cogent
would have offered cold potato well before the original depeering.

I have no specific information, but I'm guessing there is a per-mbps charge
that kicks in at certain ratio levels. Or, there may be a flat "port charge"
per month under certain conditions - Sprint did this many years ago.


Etc.

I'm having a bit of trouble figuring out Level(3)'s goal in all this. A bit
of incremental revenue? For all of this trouble? I could understand feeling
that Cogent's ratios are a violation of their peering requirements and
depeering them on principle, but if that's the case, why back down for a
little cash? 

Of course, various external pressures may have been brought to bear on
Level(3). Customers, regulators, press, creditors, etc.
