Cogent & Level 3 routing issue?

[Matthew Crocker <matthew () corp crocker com>]

Anyone seeing issues between Cogent & Level3 in NYC?

I have Sprint & Cogent for bandwidth.   Everything has been humming along for a couple years just fine.   Yesterday 
around 8:00AM my BGP session with Cogent flapped.  Now, when my Cogent BGP is up I get 100% packet loss in level3 land. 
 When Cogent BGP is down (i.e. I’m running solely on Sprint)  Everything is fine.

I have an open ticket with Cogent.  They say they have a ‘capacity issue’ with level3 that has been escalated to 
executive levels.

With Sprint & Cogent BGP UP
 I see traceroutes showing traffic leaving me on Sprint but returning on Cogent (and failing at level3).  I’m guessing 
it is the level3/cogent border

With Sprint UP & Cogent Down
 I see trace routes showing traffic on to/from on Sprint just fine.


Anyone else having issues?
