Hahahahaha. Skype has announced what was the root cause behind last Thursday’s major outage and it was you, Windows users. It seems as though it was Patch Tuesday (Windows Update) on the 14th, which caused everyone and their mother to reboot around the same time. This in turn caused a high number of log-in requests and shoddy P2P network resources resulted in what we saw last week.

Normally Skype’s peer-to-peer network has an inbuilt ability to self-heal, however, this event revealed a previously unseen software bug within the network resource allocation algorithm which prevented the self-healing function from working quickly.

Better get on that.
