The Down Detector fault tracking site recorded tens of thousands of reports for each of the services. Facebook’s own site wouldn’t load at all for about an hour on Monday; Instagram and WhatsApp were accessible, but couldn’t upload new content or send messages.
The blackout came the morning after “60 Minutes” aired a segment in which Facebook whistleblower Frances Haugen claimed the company was aware of how its platforms were being used to spread hatred, violence and disinformation, and that Facebook had tried to hide this evidence. Facebook rejected these claims.
The interview follows weeks of reporting and criticism on Facebook after Haugen published thousands of pages of internal documents to regulators and the Wall Street Journal. Haugen is scheduled to testify before a Senate subcommittee on Tuesday.
Facebook shares fell more than 5% by midday Monday, making it its worst trading day in nearly a year.
