In a blog post, Facebook explained its engineers issued a command that unintentionally took down all the connections in its network, “effectively disconnecting Facebook data centers globally.”
The outage cut off access to Facebook, Instagram and WhatsApp globally.
It also caused employees to lose access to internal tools, including those used by Facebook employees to correct such issues, the company said.
Facebook added that its program audit tool had a bug, and failed to stop the command that caused the outage.
