Facebook named the reason for the large-scale malfunction
Changes in the configuration of backbone routers caused problems that interrupted communication.
Facebook said that the failure in the work of the social network occurred due to incorrect configuration changes on the backbone routers. This was reported on Facebook Engineering's website.
"Our engineering teams learned that configuration changes to the backbone routers that coordinate network traffic between our data centers caused problems that disrupted that communication. This network traffic disruption caused a cascading effect on the way our data centers communicate, resulting in our services being disrupted," the statement said.
The company also noted that the underlying cause of the outage also affected many of the internal tools and systems that are used in day-to-day operations, making it difficult for company experts to quickly diagnose and resolve the problem.
Earlier, experts expressed the opinion that the global failure in the social network Facebook and its services occurred most likely due to unprofessional upgrade of routers by employees of the company.
Recall that the failure in the work of Facebook has become the largest in history. Access to the company's social networks and services was closed for seven hours.
