Problems with UU->Level3 last night?

Tue Nov 5 16:16:48 UTC 2002

Last night I saw an issue with connectivity between a domestic site in
Pennsylvania off of Level3's network connecting to a site on UUNet in
Australia - latency was almost triple of what it normally is...

Level3's response was of course "We don't see anything" - even with
traceroutes showing otherwise.  Did anyone else experience anything or hear
anything about it?

Latency is normally in the ~240ms range.
