Major social media services including Facebook, Instagram and WhatsApp were hit by a massive outage on Monday, tracking sites showed, impacting potentially tens of millions of users.

Users trying to access Facebook in affected areas were greeted with the message: “Something went wrong. We’re working on it and we’ll get it fixed as soon as we can.”

The outage comes a day after a whistleblower went on US television to reveal her identity after she leaked a trove of documents to authorities alleging the social media giant knew its products were fuelling hate and harming children’s mental health.
