If you can't access Facebook, Instagram, Messenger or WhatsApp, you're not alone. At approximately 18:38 Kyiv time, Downdetector began to register a surge of crash reports in all four Facebook-owned services.
Andy Stone, a company representative, said at 19:07 Kyiv time that the company is working on a quick solution to the problem, but did not mention what is at the root of the problem. The error page you see when you try to connect to the platforms suggests that the failure is due to a Domain Name System (DNS) error.
It's unclear how widespread the problem is, but Downdetector shows more than 30 crash reports for Facebook alone, with another 000 related to Instagram. According to a tweet from the official Oculus Twitter account, the issue also affects the Oculus app, store, and website.
