Cogent is experiencing two problems right now. Their automated message reports that they have a backbone problem causing latency, but they also seem to be experiencing peering problems with Sprint.
From Covad:
There may be some internal problems on the Sprint network; I'm unable to hit www.duke-energy.com from either my Covad T1 or my AT&T T1 and my users with Sprint wireless cards can't reach my VPN concentrator (Covad-connected). traceroute to 209.163.178.6 (209.163.178.6), 64 hops max, 40 byte packets 1 drawbridge.alfordmedia.com (192.168.67.254) 0.698 ms 0.279 ms 0.313 ms 2 h-74-1-2-209.dllatx37.covad.net (74.1.2.209) 2.219 ms 2.317 ms 2.177 ms 3 172.22.0.1 (172.22.0.1) 27.102 ms 16.690 ms 15.209 ms 4 192.168.38.173 (192.168.38.173) 33.027 ms 15.440 ms 12.087 ms 5 66.236.128.245.ptr.us.xo.net (66.236.128.245) 20.182 ms 16.088 ms 37.398 ms 6 p4-3-0.mar1.dallas-tx.us.xo.net (207.88.82.9) 13.000 ms 13.187 ms 15.036 ms 7 65.106.4.245.ptr.us.xo.net (65.106.4.245) 31.468 ms 13.498 ms 14.839 ms 8 p0-0.ir1.dallas2-tx.us.xo.net (65.106.4.182) 14.992 ms 18.729 ms 15.151 ms 9 peer-01-ge-3-1-0-15.dlfw.twtelecom.net (66.192.252.145) 14.835 ms 14.095 ms 20.054 ms 10 hagg-03-ge-0-0-0-460.dlfw.twtelecom.net (64.129.234.4) 45.161 ms 16.826 ms 28.240 ms 11 64-129-174-30.static.twtelecom.net (64.129.174.30) 24.740 ms 16.621 ms 14.966 ms 12 * * * (ad infinitum)
