The massively popular social network went down early afternoon with issues popping up across Facebook proper, Facebook Messenger and Instagram.
As with nearly every Facebook outage, users headed to Twitter with the hashtag #facebookdown quickly becoming the top trending topic in the United States.
Downdetector.com, which monitors websites, showed the company experiencing issues across a large portion of the U.S. and Europe in addition to issues in other areas in South America and Asia.
It is not immediately clear what caused the Wednesday issue. Some users reported seeing a message saying the site was down for “required maintenance.”
“We’re aware that some people are currently having trouble accessing the Facebook family of apps,” a Facebook spokesperson said in a statement provided to USA TODAY. “We’re working to resolve the issue as soon as possible.”
Facebook-owned WhatsApp did not appear to be immediately impacted by the outage.
