Facebook names the reason of global failure and Zuckerberg loses $5.9 billion

Facebook has named the reason of the failure in social network work, as well as services Instagram, WhatsApp and OculusVR.

On October 4, users around the world began complaining about problems with access to Facebook, Instagram and WhatsApp. The crash lasted for almost six hours. During this time, there were many rumors on the web about a hacker attack and the theft of user data. In the meantime, Mark Zuckerberg's assets fell from $122.7 billion to $116.8 billion and the company's stock price fell from $340.19 to $323.65.

But Facebook development team hastened to reassure everyone. Now we know that the cause of the failure was an error that was made when changing the routing configuration. Due to it the chain reaction in the communication channels of Data Center was launched, which led to the termination of all services.

The malfunction lasted for approximately six hours. This is the longest failure since 2008. However, 13 years ago the social network had 80 million users, while now it has 3 billion. Facebook was dead for a day at that time.

The last major disruption was recorded just over two years ago. In July 2019, users experienced access issues for an hour, and the social network experienced outages throughout the day.
