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?
