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. Dave
