Skype, однако !

Skype engineers are working on the problem, the company said. But the fix may take “a few hours,” and advanced features like video calling might not be available until after that.
So what went wrong? The company says the problem has to do with its “supernodes” — a crucial part of its peer-to-peer networking system. Almost any computer in the network can be a Skype supernode, and these act like directories for the service, telling Skype things like who is online. Skype says a problem with some versions of Skype took a bunch of supernodes down, meaning that people weren’t able to log on as normal.

Если у Вас перестал работать Skype:

Под 7 виндой заставить работать можно удалив файл
shared.xml из папки C:\Users\%username%\AppData\Roaming\Skype

Если XP, то отсюда: C:\Documents and Settings\%username%\Application Data\Skype

маководам: rm ~/Library/Application\ Support/Skype/shared.xml в терминале помогает

linux: mv ~/.Skype/shared.xml ~/.Skype/shared.xml_old
