RE: Cogent / Internap issue ??

2014-05-27 Thread Matthew Huff
Just to clarify, it's not just a traceroute issue. I can't ping nor connect to 
port 80/443 to the ip address 72.5.52.199 from our network, although I can do 
both from an external shell account. It's very possible that it's a routing 
issue on the other side, and I'm reaching out to them as well.

We are having troubles reaching services on the other side of cogent/internap 
peering. Anyone else seeing issues?

We haven't seen Cogent-related issues at SEF today and that IP address 
is currently pingable through the Cogent looking glass. From your trace, 
Internap's equipment is reachable and responding (the two last hops are 
Internap-controlled), so the actual endpoint network (beyond Internap) 
seems to be either explicitly filtering your source or sending traffic 
back to it over a different and broken path.


The Internap NOC is responsive when it comes to investigating routing 
problems, so they're a good place to turn for such concerns. If you're 
having problems reaching them or would like some external help in 
exploring the problem from inside and outside that PNAP, shoot me an 
email off-list.
