Popular VoIP service Skype appears to be suffering an outage this morning as many users complain of connection issues. The company hasn't released an estimated number of affected users, but ReadWriteWeb reports that usage numbers have fallen from 21 million to 10 million, which isn't isolated to any language or region.

Skype has officially acknowledged the problem but hasn't provided much information about the cause. It should supposedly be "Our engineers are creating new 'mega-supernodes' as fast as they can, which should gradually return things to normal. This may take a few hours, and we sincerely apologise for the disruption to your conversations. Some features, like group video calling, may take longer to return to normal," the company explained.
