In a statement posted on the company's support page, the company claims: "The disruption was initiated by a massive restart of our user's computers across the globe within a very short timeframe as they re-booted after receiving a routine software update." This is presumably the Windows updates that were sent out on Patch Tuesday last week, which required the PC to be restarted.
What is that? How has this all of the sudden become a problem for Skype? Windows computers are improved all the time by Microsoft updates, why hasn't Skype gone down before?
I think someone is pointing fingers.
