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. -John
