Cogent packet loss to Verizon in San Jose
Anyone from Cogent around? Normal support channels aren't getting me anywhere. We have been seeing consistent packet loss to Verizon over Cogent in San Jose for several days: HOST: noc-auth1.garlic.com Loss% Snt Last Avg Best Wrst StDev 1. router.garlic.com 0.0% 10 0.4 0.3 0.2 0.4 0.0 2. vl203.mag03.sfo01.atlas.cogentco.com 0.0% 10 2.2 2.3 2.1 2.4 0.1 3. te0-2-0-1.mpd21.sfo01.atlas.cogentco.com 0.0% 10 2.6 2.6 2.4 2.8 0.1 4. be2166.ccr21.sjc01.atlas.cogentco.com 0.0% 10 3.9 3.9 3.7 4.2 0.1 5. be2000.ccr21.sjc03.atlas.cogentco.com 0.0% 10 4.7 4.4 4.3 4.7 0.1 6. verizon.sjc03.atlas.cogentco.com 40.0% 10 80.0 80.8 79.9 81.8 0.7 7. so-1-0-0-0.SJC01-CORE-RTR1.verizon-gni.net 30.0% 10 82.2 87.9 81.1 114.6 11.3 8.

This has been going on nationwide between Cogent and other peering partners since early 2013 (and in some cases before), but especially between Cogent and Verizon. It's not a technical problem, but a political one. We resolved our issue by working with our upsteam providers to reconfigure our routing and advertisements to avoid cogent, otherwise, I don't think there is any solution coming within a reasonable timeframe ---- Matthew Huff | 1 Manhattanville Rd Director of Operations | Purchase, NY 10577 OTA Management LLC | Phone: 914-460-4039

Issues in NYC today too. We confirmed traffic coming in from VZW as well as Comcast through Cogent to us both seeing drops at that same point.
