Microsoft's Black Tuesday bandwidth impact?

Thanks.  Slide 8 of your PDF shows that what an ISP would see in a P2P heavy
environment is that after the automatic application of Windows Updates a
drop in traffic should be seen because the P2P desktop applications don't
automatically restart after their PC reboots.

I guess that means that if I don't see a drop a traffic, my end-users are
behaving themselves!

I made a short presentation related this topic in NANOG38.

Recently, we can see a decline during the maintenance
at the major video streaming site in Japan.
