Just posted on the Skype corporate blog by Skype's Villu Arak:
Take a deep breath. Skype is back to normal.
On Monday, we’ll provide a more detailed explanation of what happened. Until then, we’d like to apologize and thank you. Precisely in that order. We know how difficult and frustrating the past two days have been. And still, your good wishes kept flowing in. Thank you for the amazing patience, trust and support!
Monday's deets will be interesting. Can't wait. You'll be among the first to know.
