About 10 minutes ago we stopped being able to pass traffic through cogent. I de-peered us from Cogent, and everything appears better. When I call cogent, all I get is a busy signal (must be a major outage). Anyone else seeing anything?
I saw packet loss to a destination in Troy, NY which has Cogent as one of its upstreams as well (and it was the Cogent path which I saw packet loss/disruption on). This was observed from a non-Cogent multihomed network in Reston, VA. Started at at 11:54 Eastern and ended about 20 minutes later.
Replying to myself, here is the path on which I saw disruption (no problems now/at the time of the mtr -r below): ryan@vicious:~$ mtr -r -w rpi.lily.org HOST: vicious Loss% Snt Last Avg Best Wrst StDev 1. 192.168.152.199 0.0% 10 0.3 0.2 0.2 0.3 0.0 2. 67.23.118.177 0.0% 10 0.8 0.8 0.6 1.0 0.1 3. te0-1-0-0.nvarsx-COR00.yellowfiber.net 0.0% 10 1.5 1.4 1.2 1.7 0.2 4. te0-0-0-1.nvarsx-cor01.yellowfiber.net 0.0% 10 1.3 1.4 1.2 1.8 0.2 5. te0-0-0-2.nvaiad-cor00.yellowfiber.net 0.0% 10 1.5 1.4 1.2 1.7 0.2 6. xe-9-0-6.ar1.iad1.us.nlayer.net 0.0% 10 4.7 3.3 1.9 5.2 1.2 7. ae0-30g.ar2.iad1.us.nlayer.net 0.0% 10 3.9 3.7 2.4 7.5 1.7 8. 144.228.205.97 0.0% 10 1.7 3.2 1.2 17.3 5.0 9. sl-st31-ash-0-8-0-2.sprintlink.net 0.0% 10 2.5 2.5 1.7 5.7 1.1 10. 144.232.8.14 0.0% 10 1.7 1.8 1.6 2.1 0.2 11. te0-2-0-5.mpd22.dca01.atlas.cogentco.com 0.0% 10 3.0 2.8 2.5 3.1 0.2 12. te0-3-0-4.mpd22.ord01.atlas.cogentco.com 0.0% 10 21.7 21.5 21.1 21.7 0.2 13. te0-6-0-17.mpd22.jfk02.atlas.cogentco.com 0.0% 10 47.4 48.2 47.1 49.6 0.9 14. te3-3.ccr01.jfk01.atlas.cogentco.com 0.0% 10 46.6 44.3 40.0 48.7 3.7 15. te7-1.mag02.jfk01.atlas.cogentco.com 0.0% 10 47.3 47.7 46.1 49.4 1.0 16. 38.122.9.54 0.0% 10 51.6 50.7 46.6 52.5 1.6 17. vccfr7-39-33.net.rpi.edu 10.0% 10 50.8 53.6 48.1 85.2 11.9 18. ??? 100.0 10 0.0 0.0 0.0 0.0 0.0 ryan@vicious:~$
