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. ---- Matthew Huff | 1 Manhattanville Rd Director of Operations | Purchase, NY 10577 OTA Management LLC | Phone: 914-460-4039 -----Original Message----- From: NANOG [mailto:nanog-bounces@nanog.org] On Behalf Of Matthew Huff Sent: Tuesday, May 27, 2014 2:25 PM To: nanog@nanog.org Subject: Cogent / Internap issue ??

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. -John
