Facebook services restored work

“We've been working hard to regain access to our app and services, and we're happy to announce that they're coming back online,” Facebook said on Twitter.

The company apologized for the global disruption to "a huge community of people and companies." Later, Facebook CEO Mark Zuckerberg personally apologized.

“I’m sorry for today's disruption — I know how much you rely on our services to stay in touch with the people you love,” he wrote on his page.

The company that operates the public domain name system (DNS) service, Cloudflare, indicated that on October 4, Facebook stopped providing information about the route to its servers. This caused a thirtyfold DNS load as both users and applications tried to log onto Facebook. Facebook has confirmed that the cause of the failure is a misconfiguration of network equipment.

After the giant " fell ", users began to state interruptions in the work of Google, Twitter, Telegram, TikTok, Tinder, Netfix, Zoom and other services.

Shares of Facebook, Alphabet, Class A (owner of Google), Apple, Twitte, as well as shares of the NASDAQ exchange, where technology companies are traded, fell on the exchanges.

Doug Madori, director of Internet analysis at network monitoring company Kentik, told The Washington Post that the reason for the failure could be a problem with the dynamic routing protocol BGP. He noted that it is probably a matter of Facebook's BGP routes that allow routers to communicate.

Facebook noted that the failure of the services did not lead to the leakage of user data. At the same time, we recall that yesterday it became known about the largest "drain" of personal information of one and a half billion users.
