This appeared to bite my Level3-connected bandwidth as well.

sigh.  is this an attack by a black hat, or by an rir and researchers
who do not know how to say "oops, sorreee!?"

Even weirder, a remote server running SmokePing showed a 11ms increase
in latency from 24ms to 35ms, which started after service was restored,
then a drop at precisely 11:00PM Eastern back to original, lower levels
of latency.

That is,

4:45PM 24ms on Level3
4:50PM to 5:07PM - Level3 outage
5:08PM to 10:59: 35ms on Level3
11:00PM and after: 24ms on Level3

Very odd.
