Skype was once again down again (June 7) with users around the world not to be able to sign in at all. Skype acknowledged that a "small number of you may have problems signing in to Skype." The company added that a configuration problem caused some Skype users to be disconnected from teh service.

"We've identified the cause of the problem, and have begun to address it. If you've been affected, you should start to see improvement in the next hour or so. You shouldn't need to manually sign back in to Skype - it should reconnect automatically when it's able to do so," Skype said.

The service was gradually restored within a 3-4 of hours.

This is the second time within almost 10 days Skype hit with outage. In late May, the popular internet phone service had crashed throughout the world for almost a day. The company had released a manual workaround as well as new software updates in order to allow users of Skype on Windows or a Mac, to sign in again.

Last December, millions of people around the globe had been also hit by another outage at Skype. Skype had said that some computers or 'supernodes' used by the service as phone directories and were essential for the operation of Skype had been taken offline, causing the problem.
