VoIP and group video conferencing provider and latest buy of Microsoft, Skype has crashed, as users from across the world are citing sign-in and communication issues.

The Inquirer reported that Skype service crashed at about 12:15pm UK time.

Skype's response which was placed on Twitter read: 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.

Soon another message said, Thanks for your patience – we’ve identified the problem and will be rolling out a fix soon.

Engadget stated that the problem was not universal and the fault seemed to be in the latest version of Skype.

Skype faced a similar outage in Dec. 2010 which was more widespread in nature.

The outage report comes just days after Microsoft acquired Skype for $8.5 billion.
