Facebook went down for millions of users across the world on Monday.
Visitors to Facebook were greeted with a message reading "sorry something went wrong. We're working on it and we'll get it fixed as soon as we can."
This is the second time in a week that the hugely popular social networking website has experienced an outage. Facebook went down on September 24th for a brief time, much to the frustration of the social media giant's one billion active users.
