If a server that can handle 500K packets/sec is sitting behind a pipe that
maxes out at 400K packets/sec, it won't be affected when the pipe is flooded.
Most likely, half your packets were being dropped 2 or 3 hops from the
server (where the DDoS starts converging from multiple sources). So we
probably can't pin a "bold-faced lie" on VeriSign this time. Dissembling
and misleading perhaps, but not a total lie (unless somebody can prove that
the pipe still had capacity and wasn't dropping stuff)
