Down Detector UK recorded a peak of more than 50,000 Facebook down reports.
While the independent outage monitor also registered a peak of more than 8,000 Messenger down reports.
Now, following the international outage, a whistleblower is to testify in front of the US Senate Committee on Commerce, Science and Transportation Consumer Protection, Product Safety and Data Security Subcommittee.
The hearing is on ‘Protecting Kids Online: Testimony from a Facebook Whistleblower’ with testimony from former Facebook official Frances Haugen.
Mr Haugen recently alleged the company had disabled safeguards designed to prevent misinformation, dissolved a unit on civic integrity.
He also claimed the social media giant changed the algorithms that govern what appears on users’ news feeds in a way that “contributed to more divisiveness and ill will”.
The Facebook outage began just before 5pm UK time – and over five hours later is still rumbling on.
Besides the main Facebook service, Messenger, WhatsApp and Instagram are all experiencing service issues.
