Facebook blames ‘misconfiguration change’ for global outage

Facebook, Instagram and WhatsApp are now backed up after being shut down due to a global outage on Monday.

The widespread disruption was blamed on a “misconfiguration change,” with Facebook saying in a statement: “Our engineering teams have learned that configuration changes to the core routers that coordinate network traffic between our data centers caused issues that interrupted that connection. .

“This disruption to network traffic has had a ripple effect on the way our data centers communicate, bringing our services to a standstill.”

The company did not specify in a blog post late on Monday who changed the configuration and if it was planned.

Several Facebook employees, who declined to be named, told Reuters earlier that they believed the outage was caused by an internal error in how internet traffic was routed to its systems.

Employees said the failure of internal communication tools and other resources that depended on the same network to function exacerbated the error. Security experts said an inadvertent error or sabotage by an insider was reasonable.

“We want to make it clear at this time that we believe the root cause of this outage is a misconfiguration change,” Facebook said in the blog.

The Facebook outage is the largest that has been tracked by web monitoring group Downdetector.
