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. http://www.nanog.org/mtg-0610/tarui.html Recently, we can see a decline during the maintenance at the major video streaming site in Japan.

Every month I look at my upstream bandwidth graphs and I see no blip in
hours before 3 am on Microsoft's Black Tuesday. I would think that with
the the
thousands of PCs out on our network downloading updates around that time that I would see *something*. I know every Black Tuesday I see my three PC's blinking a logon screen.
Are MSFT's monthly updates really a non-event in regards to internet bandwidth?
