According to The New York Times, Facebook experts are still trying to determine the source of the instability:
According to the New York Times, a team of Facebook employees was sent on Monday, 4, to the company’s data center in Santa Clara, California, to attempt a “manual reset” of the servers.
According to the American newspaper, Facebook experts are trying to determine the source of the instability, however, two members of the security team said, on condition of anonymity, that a hacker attack is very unlikely.

With the technical failure, which affected Facebook, Instagram, and WhatsApp, the company’s shares, which has nearly 2 billion active users daily, opened lower and increased losses in the afternoon, plummeting 5.6% at 4:40 pm (Brasilia time). ) on the New York Stock Exchange.
According to experts, Facebook was inaccessible because users were not being directed to the correct place by the Domain Name System (DNS). Facebook itself controls the relevant settings. DNS allows web addresses to take users to computers where the information they are looking for is.
A similar outage at cloud computing company Akamai Technologies took down several websites in July. Security experts following the situation said the outage was likely caused by a configuration error that left directions to Facebook’s servers unavailable.
This could be the result of an internal error, although an internal sabotage action is theoretically possible. An external attack is considered less likely by experts. On the other hand, massive denial of service attack that could bring down one of the most popular websites in the world would require coordination between powerful criminal groups or a very innovative technique.
Facebook acknowledged that users were having problems accessing their apps, but did not provide any specifics on the nature of the problem or how many were affected by the outage. “We are working to get things back to normal as quickly as possible and we apologize for any inconvenience,” Facebook wrote on Twitter about 30 minutes after the first reports of access issues.
Facebook’s response was made much more difficult because employees lost access to some of their own tools during the crash, people who follow the matter say. Downdetector, a site that only tracks service outages by collecting status reports from a number of sources, including user-submitted errors, showed that there were more than 50,000 incidents of people reporting problems with Facebook and Instagram.
The outage could be affecting a large number of users. Meanwhile, Facebook’s instant messaging platform WhatsApp also dropped to over 35,000 users, while Messenger dropped to nearly 9,800 users. Facebook experienced similar widespread outages with its app package this year, in March and July.
