The social network Facebook (Facebook) and its platforms Instagram and WhatsApp (WhatsApp) do not work today in many parts of the world.
The company said it is "aware that people are having trouble accessing the Facebook app" and is working to restore access.
It was not stated what caused the outage, which began around 11:45 a.m. local time.
Users reported not being able to access Facebook in California, New York and Europe.
Facebook is going through a major crisis and has come under fire after internal documents published by "The Wall Street Journal" showed that the company is aware that Instagram is harming the mental health of young users.
Frances Haugen, who worked as a product manager on the Facebook team, revealed her identity on the television program "60 Minutes" on Sunday as a whistleblower who helped launch the Wall Street Journal investigation and the Senate hearings on the damage. that Instagram inflicts on teenage girls.
