"Hey, is it just me or you cannot log into Skype too?" - probably one of the most frequently used phrases today. Millions of people across the world, who use Skype for personal and corporate needs were frustrated to find the popular service unavailable. And yes, it's still not working properly.
Basically, you can launch the client, but your status will be 'offline' and you won't be able to change it. Video and voice calls don't seem to work as well.
