UUnet West Coast glitch?

  • From: Steve Francis

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?
