Server down

Facebook Inc.’s services went offline for as much as six hours Monday before some of them were restored, an extended outage that disrupted access for users and businesses around the world and left the tech company flailing for a solution.

The company apologized for the outage, which affected its core platforms and apps including WhatsApp, Instagram, and Facebook Messenger—and which an outside tracking firm said appeared to be the most widespread in its history. Facebook said the problem was due to networking issues. Outside experts said it appeared to stem from a change the company made to networking instructions for access to its systems.
