RE: Nationwide Routing issues with Wiltel

FYI Level 3 had a pre-existing peering issue with UUNet/Alternet at the
end of last week that was due to issues on an oc48.  If that hasn't been
resolved, it is a separate (or compound) issue compared to today's
Wiltel outage.  We have been told by L3 that it was an outage on the
legacy Wiltel network.  From what we gather they had to reroute a lot of
that traffic onto other parts of their network, causing increased total
traffic and then latency, but that has not been confirmed to us.

I can confirm this as well, although have no proof (at this point)
that Layer3 is necessarily to blame.  We (or rather the company I
work for) are seeing similar between MCI/UU/Verizon and WCG when
reaching some of our clients:
