If you cannot access Facebook, Instagram, Messenger or WhatsApp, you are not the only one. Starting from around 11:38 ET, downdetector began to record a surge in blackout report in the four services owned by Facebook. Andy Stone, a company spokesman, said at 12:07 ET that the company worked to solve problems quickly. The error page you see when trying to connect to the platform shows a domain name system (DNS) error is responsible for its blackout. At 3:52 ET, CTO Mike Schroepfer, which is scheduled to leave the company next year, Facebook said sincerely apologized for his blackout but stopped offering an explanation of what caused it.

On Monday afternoon, Facebook, Instagram, Messenger and WhatsApp have begun online for several people.

It is not clear how broad the problem is, but the downdetector shows more than 30,000 blackout reports for Facebook only at one point, with 20,000 other bound to Instagram. Per Tweet from Oculus Twitter’s official account, the problem also affects the Oculus, Store and Website applications.

Need Facebook today to solve this problem. According to the New York Times, blackouts issue work, the company’s internal communication platform. In addition, employees are reported to not be able to receive external emails at this time.

PER journalist Brian Krebs, Note DNS Facebook was withdrawn from the global routing table around this morning. “We don’t know why this change was made,” Krebs wrote in a tweet. “It can be a result of internal changes, a system or update that is wrong. That’s all speculation at this point why. Facebook alone controls the DNS record.”

Back in July, Akamai Technologies, one of the largest content delivery networks in the world, through similar blackouts, which leads to most of the internet, including platforms such as PlayStation Store, Tiktok and LastPass, becoming inaccessible. Akamai finally fixes the problem later on the same day.
