Facebook and the platforms the social media giant acquired, Instagram and WhatsApp, were hit by a sudden massive outage that caused millions to lose access to Facebook's apps and products. 

Tracker Downdetector was showing outages in heavily populated areas, such as Washington and Paris, with problems being reported as early as 6:45 PM occupied Jerusalem time.

"We're aware that some people are having trouble accessing our apps and products," Facebook spokesman Andy Stone said on Twitter.

We’re aware that some people are having trouble accessing our apps and products. We’re working to get things back to normal as quickly as possible, and we apologize for any inconvenience.

Users trying to access Facebook in affected regions were met with a message saying: "Something went wrong. We're working on it, and we'll get it fixed as soon as we can."

The outage even affected other Facebook services and products, such as Oculus and Facebook Workplace.

As Facebook and its services and platforms went down, #FacebookDown started trending on Twitter, and users were reporting the issues they were facing.

The outage Facebook is facing comes a day after a whistleblower went on CBS News' 60 Minutes to reveal her identity, after leaking internal documents to authorities stating the company knew its products were fueling hate and harming children's mental health.
