Folks: This is a fascinating case study, but we don't yet have enough information to really learn from it!
http://heartbeat.skype.com/2007/08/what_happened_on_august_16.html Questions: 1. Why did the Windows update on "Patch Tuesday" of August 14 cause this problem when the previous month's Patch Tuesday didn't. 2. Why did the disruption to the Skype network begin on on Thursday if the Microsoft patches starting updating customers' computers on Tuesday? 3. Why didn't the Skype "self-healing" behavior work? Was it due to the unusual scale/scope? Was it due to reliance on centralized resources that were themselves overloaded at that time? Is the same mechanism used for failing-over live phone calls as is used for "self- healing" server access? There are probably other questions we should be asking. If anyone can give useful insight into the technical events, that would be great.
