At the IETF Plenary, Bernard Aboba showed a graph of spam, with a marked uptick since SoBig.F in August. My guess is worm-deposited spam relays, though Joel's guess of Nachi or Welchia can't be ruled out, either, without flow data.
I would say all of the above, plus the normal "back from summer holidays, weather is getting worse, lets go on-line instead" phenomena, and "there is now more to do online including cool higher bandwidth net content" all add to higher usage. But I would certainly say worm traffic is a big one. ---Mike
