recently skype suffered a world wide outage. it was reported on skype blog: http://heartbeat.skype.com/2007/08/what_happened_on_august_16.html
while skype put the description well, certain other reports fuelled the rumor mills on the problem being due to the Microsoft patch release.

the entire episode has been thoroughly investigated by both skype and microsoft and the findings are presented here: http://blogs.technet.com/msrc/archive/2007/08/20/questions-about-last-tuesday-s-release-and-skype.aspx

In brief what happened was that skype had architected its applications in a particular fashion with a known but uneventful bug. Once the patch was applied, that bug in skype server application became active and prevented recovery of the network!
