We just saw RTT times to a bunch of sites (yale, ucsb, cisco, yahoo, mci) all go up to 3 second RTT with lots of loss. The one traceroute I did before it corrected itself showed long delays once traceroute entered UUnet - but could be the return path. (This was from an Internap colo site, so there is often assymetry.) I saw the same delays out of another TimeWarner connected site... Anyone else know what was going on? trace www.mci.com Translating "www.mci.com"...domain server (63.251.224.9) [OK] Type escape sequence to abort.
