At about 9:31 a.m. PST today (12:31 p.m. EST), Facebook went down. This is the second time the social network has gone down in just a week.

VB staff from across the world confirmed they couldn’t reach the social network. Some are seeing a generic “Service Unavailable” error, but most are seeing a “Sorry, something went wrong.” message followed by “We’re working on it and we’ll get it fixed as soon as we can.” This is of course a placeholder page.

A quick check at DownForEveryoneOrJustMe confirmed the issue was widespread: “It’s not just you! http://facebook.com looks down from here.”

We have contacted Facebook for more information and will update you if we learn the cause of the outage. Facebook did not get back to us last week in regards to what cause that outage.

Update at 9:41 a.m. PST: And just like that, Facebook is coming back.

The first outage lasted an average of five minutes for most users. This one lasted some 10 minutes for most. We will update you if Facebook offers an explanation.

Update on September 28: Facebook went down again on September 28.
