Facebook is undergoing one of its most widespread and persistent system outages, with users across the globe unable to access its social network and services from Instagram to Messenger for much of March 13.
From about noon New York time, users encountered only partially loaded pages or no content at all, accompanied by a message saying an error had occurred. Several brand marketers tweeted that Facebook’s ad-buying system was down as well. As of about 6.30pm, Facebook said it was still investigating the overall impact, “including the possibility of refunds for advertisers”.
