Facebook has apologized to users for the inconvenience caused by the shutdown of its systems, noting that access to the social network has already been restored. How reported on the Facebook engineering group site, the root cause of this failure also affected many of the internal tools and systems the company uses in its day-to-day operations, making it difficult to quickly diagnose and fix the problem.
Eventually, the engineering team found out that the failure was due to a reconfiguration of the backbone routers that coordinate network traffic between the company’s data centers. “This disruption to network traffic had a cascading effect on the way our data centers were connected, resulting in our services being stopped,” – reported Facebook.
The statement emphasizes that the main reason for the failure was an incorrect configuration change, and there is no evidence that user data has been compromised as a result.
The shutdown of Facebook, Instagram and WhatsApp hurt the market position of the company, whose shares plummeted by more than 5%. In a matter of hours, Facebook CEO Mark Zuckerberg lost about $ 6 billion.
