Skype, the globally popular video chat service, is down this morning for many users, according to the company.

Users of the video and voice chat service reported to the company that they were unable to sign on. Skype said they have identified the problem and are fixing it currently.

Some of you may have problems signing in to Skype and making calls. We're investigating and hope to have more details to share soon, the company tweeted first. It then followed with, Thanks for your patience - we've identified the problem and will be rolling out a fix soon.

In the mean time, Skype has offered its users a manual fix. The fix is below.

This is not the first time Skype has experienced major outages. Back in December, the company had widespread outages, which were fixed over the period of a day.

Skype was recently bought by Microsoft for $8 billion. The two companies will merge together, and Skype will become a division within Microsoft. The popular service had 170 million connected users and logged over 207 billion minutes of voice and video conversations in 2010.
