FW: [OCCAID] Late night packet loss EWR <-> BOS

[James Jun]

Hmmmmm... weird indeed :)  I'm wondering if the path from Comcast to
Sixxs-EWR is the cause may be?  I don't think we had any complaints from
native downstreams in Boston when connecting to east coast sites, since the
EWR-BOS circuit got fixed..

The only active maintenance & network related issue going on at OCCAID BOS
pop right now is just native peering for Boston University from what I can
tell.. which shouldn't affect anything at all.

Can you try getting a 2nd account via SixXS ORD (granted, there will be more
latency obviously) and see if you have the same instability problem with
that?  Thanks!
