Now for the moment that we’ve all been waiting for. Many of us have speculated about the different reasons that Skype went down last week. Some said that it was caused by Russian Hackers, but Skype came out to deny this.
Skype needed to answer the world, though. If you read the Heartbeat blog today, you will see their official statement:
On Thursday, 16th August 2007, the Skype peer-to-peer network became unstable and suffered a critical disruption. The disruption was triggered by a massive restart of our users’ computers across the globe within a very short timeframe as they re-booted after receiving a routine set of patches through Windows Update.
The high number of restarts affected Skype’s network resources. This caused a flood of log-in requests, which, combined with the lack of peer-to-peer network resources, prompted a chain reaction that had a critical impact.
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. Regrettably, as a result of this disruption, Skype was unavailable to the majority of its users for approximately two days.
The issue has now been identified explicitly within Skype. We can confirm categorically that no malicious activities were attributed or that our users’ security was not, at any point, at risk.
Sounds like people need to modify their default Windows Update settings. Or do you all think that this is a cover-up answer? Interested in hearing your thoughts on this one.
