Remember the Skype mega outage that lasted for 30 hours and left eighty percent of their subscribers in the dark? Well, Skype has posted how it all went down. A new blog post, which you can read here describes the event.

I wouldn't buy that for a dollar!

The blog post says “a cluster of support servers responsible for offline instant messaging became overloaded. As a result of this overload, some Skype clients received delayed responses from the overloaded servers. In a version of the Skype for Windows client (version 5.0.0152), the delayed responses from the overloaded servers were not properly processed, causing Windows clients running the affected version to crash.”

It explains the entire process in detail, but the short version is that of 25–30% of supernodes crashed in the P2P network, resulting in an increased load on the remaining supernodes. This had a domino effect as the traffic that resulted to the supernodes that was about 100 times what would normally be expected at that time of day.

While everything is up and running now, Skype has decided to refund its customers for the loss of service, it’s doing that by giving them a voucher for $1. Yeah, no need to rub your eyes in disbelief, it's only $1. If you think that’s a low amount, then do understand that a dollar in skype credit will allow you over 30-50 minutes of calling time to various countries.

With all the negative publicity Skype had received for the outage, they could have done better than just a dollar, though.
