Unoffical sources say that Level 3 sent a depeering notice to Cogent a 
month ago, for a disconnection on either the 15th or the 16th of 
September. Based on the fact that Cogent is offering 0 commit ports to any 
Level 3 customers they can find (at 50% of their L3 pricing), it looks 
like they're preparing to shift as much traffic off as possible, and put 
the rest on transit. With any luck (if you're a Cogent or L3 customer at 
any rate) they won't be blackholing each other. Guess we'll find out this 
week. :)

As for the path through Asia, sounds broken, send the traceroute to 
customer support and tell them to get it fixed.
