Oh man, I have to jump in here for a moment.  Not that I agree with
what happened, but to refute your claim that Cogent can get L3
elsewhere, it goes both ways.  L3 can also get Cogent connectivity
elsewhere.   This is a big game of chicken, it will be interesting to
see who backs down first.

Well, as I somewhat said above, there will always be three sides to
every story.  Side 1, Side 2 and the truth.  Each side has a case,
it's up to the lawyers now to sort it all out.
