Om Malik says that eBay's management was nowhere to be found during the crisis, but
finally, more than 36 hours after the outage occurred, Skype explained the disruption was caused by the latest Windows update, which resulted in an abnormally high number of restarts over the two
days.
Spokesman Villu Arak issued an explanation on Skype's Heartbeat blog, saying the mass restart uncovered "a software bug within the network resource allocation algorithm which prevented the self-healing function from working quickly." The result was a disruption "unprecedented in terms of its impact and scope."
