Has anyone noticed excessively high latency between Global Crossing and
AT&T?  From what I've gathered, the PNIs between Global Crossing and AT&T
are completely maxed out.  The word is AT&T will not increase peering
capacity with Global Crossing since their in bankruptcy protection.  I am
certain that this is affecting a large number of both Global Crossing and
AT&T customers.  I think it's fair to say that both Global Crossing and
AT&T are amongst the larger Tier 1 providers out there, it's shameful that
they can't come to an agreement on upgrading capacity.
