Skype, one of the world's most popular forms of video communication through the internet has crashed. This will inhibit communication for millions of users who are trying to talk to their relatives or loved ones at home for the holidays. The company has acknowledged the outage through a series of tweets.

Skype also gave some more information on the outage through a blog post. Here is something Peter Parkes, Skype's Blogger-in-Chief stated in the post:

"Skype isn’t a network like a conventional phone or IM network – instead, it relies on millions of individual connections between computers and phones to keep things up and running. Some of these computers are what we call ‘supernodes’ – they act a bit like phone directories for Skype. If you want to talk to someone, and your Skype app can’t find them immediately (for example, because they’re connecting from a different location or from a different device) your computer or phone will first try to find a supernode to figure out how to reach them.

Under normal circumstances, there are a large number of supernodes available.Unfortunately, today, many of them were taken offline by a problem affecting some versions of Skype. As Skype relies on being able to maintain contact with supernodes, it may appear offline for some of you."

Skype's engineers are working non-stop to get new "mega-supernodes" up as fast as they can. It may take a few hours, however, until everything is back up and running.

This issue with the communications network could cause a huge ammount of customer disappointment as many people rely on the service to stay in touch with their loved ones during the holidays. Skype may have to work very, very hard to get these people happy again, however, the relief when the serivce is back up and running may be just enough to keep people satisfied.
