What are the causes of Instagram, Facebook and WhatsApp social media outages?

  • On the evening of October 4, there was one of the largest disruptions in the work of Facebook services.
  • The reason for the failure was DNS records that have disappeared from the global routing tables.
  • Social networks Facebook, Instagram and WhatsApp messenger were unavailable for about 6 hours.

Several services on Monday October 4thAmerican corporation Facebook were unavailable around the world. The failure occurred at about 18.30 Moscow time and initially affected Facebook, but later WhatsApp and Instagram owned by the company also "lay down".

What are the causes of Instagram, Facebook and WhatsApp social media outages?

Presumably, the cause of the problem lies inDNS records that have disappeared from the global routing tables, that is, in the links missing from the system between the domain name and the IP address of the server on which the site is actually located.

A similar version is confirmed by sourcesmajor media outlets. Brian Krebs, a journalist for the Independent, also said on his Twitter that the error arose due to a planned update of BGP (Dynamic Routing Protocol), and, according to him, the update blocked access for remote users, and therefore only people with physical access, which was also complicated.

“Information from a reliable source:the person involved in the Facebook recovery said the failure was caused by a standard BGP update that went wrong. Due to the update, access to remote users was blocked, and people with physical access did not have network / logical access. "

The situation was slightly aggravated by the fact that employeescompanies were unable to get to their jobs to assess the magnitude of the problem because the badge system also failed. This was reported by the journalist of The New York Times Shira Frenkel on her Twitter.

“I talked on the phone with someone who works inFacebook, and I was told that this morning, employees were unable to get into the office to begin assessing the extent of the outage because their passes did not work and did not open doors. "

As a result, Facebook social networks did not work for about 6 hours, and the situation began to improve only around 01:00 Moscow time. At the moment, all services are working.

Among other things, there was news that onspecial forums sell a huge collection of personal data of Facebook users, which has information about more than 1.5 billion people. Most likely, this is just a coincidence, since the failure was not associated with an attack, and the seller of the collection assures that all the data was collected using parsing (directly from the pages).

The failure of Facebook services caused not onlya wave of discontent of millions of users, he also became the reason for the emergence of many jokes and memes. A significant part of them concerned the position of competitors and ridiculed the problems of FB, while praising Twitter and Telegram.

Against the background of all the problems with Facebook services, the fake account of Mark Zuckerberg wrote that Bitcoin never turned off.

“Hello, it looks like we have a problem with Facebook. We will try to resolve them as quickly as possible. For those who don't know, Bitcoin has never been disconnected. I suggest you use it. "

In fairness, it is worth noting what exactlyin this case, decentralization would not have helped in any way, since the problem did not come from the fact that Facebook's servers are centralized. In any case, decentralized social networks are more reliable because they do not have a single point of failure. Therefore, we recommend having a couple of accounts on decentralized social networks in case your favorite centralized services stop working.
