Facebook revealed in an official blog post on Monday evening that the six-hour outage across its platforms including Instagram, Messenger, Whatsapp, and OculusVR were caused by configuration changes to its routers, APA reports citing Independent.
The company said these changes disrupted network traffic between the company’s data centres. However, it said it has no evidence yet that user data was compromised as a result of this downtime.
“This disruption to network traffic had a cascading effect on the way our data centres communicate, bringing our services to a halt,” the company noted.
It said the router configuration changes also impacted many of the internal tools and systems employees used in day-to-day operations, complicating their attempts to quickly diagnose and resolve the problem.
