I think there was something going on between Qwest and L3,
I saw the same thing with traffic coming from a network I
have equipment on which is connected with Qwest and tracing
to our home AS which has L3 amongst others.  I set a
community for L3 to not advertise my prefixes to Qwest to
get around it.  It appears back to normal now though, I
just tested.
