Facebook, Messenger and Instagram are back online after users flooded X with complaints for an hour and half.
Angry users found themselves suddenly booted out of their accounts, making them think they'd been hacked and their personal details stolen.
The issues appeared around 10:20am ET (3:20pm GMT) and impacted both apps and websites – although Meta's WhatsApp was unaffected.
Along with the US, the outage reached the UK, parts of Europe, China, Australia and Mexico – leading to Meta's stock price falling, according to Daily Mail.
