The latest news from Skype about their recent major outage is pointing the finger towards the autmatic Windows Update feature. Well, to be fair, they are actually blaming a “a previously unseen software bug within the network resource allocation algorithm which prevented the self-healing function from working quickly.” But the latest post on the Skype blog indicates that the chain reaction was initiated when a large number of Skype clients were rebooted in the same timeframe, due to a routine Windows Update.
While it does seem plausible that a massive concurrent restart of Skype clients could cause some grief for Skype’s network, that doesn’t explain why it took 2 days to restore service. And I’m also left wondering why previous Windows Updates haven’t caused similar problems. What do you think, is there more to this story?
