Facebook outage was caused by maintenance error, company says

Dallas, Texas (US): An error during routine maintenance on Facebook Inc.’s network of data centers caused Monday’s collapse of its global system for more than six hours, leading to a torrent of problems that delayed the repairs, the company said.

The Facebook outage was the largest that Downdetector, a web monitoring firm, said it had ever seen. It blocked access to apps for billions of users of Facebook, Instagram and WhatsApp, further intensifying weeks of scrutiny for the nearly $1-trillion company.
