Skype Identifies Causes of Two-day Outage

A huge number of users rebooting their PCs after last week's Windows Update from Microsoft triggered instability in Skype's peer-to-peer network, leading to the two-day outage for the service. The service was back to normal on Sunday.

In blog entry, Skype's Villu Arak said the high number of restarts affected Skype's network resources in an unforeseen way. Skype's network resource allocation algorithm was unable to keep up with the flood of log-ins as the rebooted PCs came back online. Skype said it has introduced a number of improvements to its software to ensure that the chain reaction does not repeat.
