Facebook went down for some users Thursday, but appears to be back up and running for others. The website “Is it Down Right Now?” lists Facebook as having “service disruptions.”
Visitors to Facebook.com were greeted by the message, “Sorry, something went wrong” instead of the usual Facebook homepage when visiting on the web, starting at about 12:30 p.m. Eastern Time on Thursday. Facebook’s mobile apps didn’t appear to be affected.
Facebook’s app status dashboard shows a “major outage” beginning at approximately 12:30 p.m. ET. The service reports its key Facebook Graph API — the core software that apps use to read and write to Facebook — became unavailable at that time.
