Does anyone have any details about the Cogent outage that started 
this morning (9am GMT-400) and is still continuing ?   If its a fibre 
cut between Montville (NJ?) and Cleveland OH 
(http://status.cogentco.com/) why is it so bad in Chicago and Albany 
locations ?  Is there really that little excess capacity ?

My connection out of Toronto is pretty bad via Albany
