Facebook-owned properties, including Instagram, WhatsApp and Messenger, were hit by sweeping outages Monday.
The issues started around 11:45 a.m. ET, according to DownDetector, and were hitting users globally.
Shortly after noon, Facebook’s site returned a message that read, “This site can’t be reached.”
Twitter users quickly made “#instagramdown” and “#facebookdown” trending on the platform in response to the outages.
Shares of Facebook were down nearly 5 percent on what was already a tough day for the Big Tech stock.
Social media users took to Twitter to complain about the outages and how they tried to restart their internet connection when they could no longer access the Facebook-owned platforms.
