Skype has rolled out software patches and program updates that the company says will restore service for the "small percentage" of its users that have been unable to sign in to its service, the company announced Friday.

Skype says on its website that a corruption problem on computers using Windows, Linux or Macintosh operating systems are behind the access denials.

"Earlier today, a corruption occured in a small percentage of users' systems that resulted in some of our community not being able to sign in to Skype," wrote blogger Peter Parkes on the company's blog.  Parkes detailed the various updates the company has released: a new version of Skype for Windows is already out and an update for Skype for Mac is planned for Friday. 

Linux users were told to follow instructions for a manual update.

A massive, days-long outage in late December left as many as 10 million people unable to use the wildly popular Internet telephony service, which is being purchased by Microsoft Corp. for $8.5 billion. This outage is dramatically smaller, Skype said.

About 170 million people worldwide use Skype regularly for calls and chats.

Skype said individuals using its service on their cell phone, television or other device should be able to continue to sign in as normal.
