Having trouble accessing Facebook or Instagram on Wednesday afternoon? You weren't alone. 

The massively popular social network went down early afternoon Eastern time with issues popping up across Facebook proper, Facebook Messenger and Instagram around the world. 

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 Wednesday's issue. Some users reported seeing a message saying the site was down for "required maintenance," while others were able to get the social networks to briefly load before discovering that functionality was limited.  

"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.
