In the past hour, Facebook’s services have collapsed across the world, and almost all of its sister services have been affected, such as Whatsapp, Instagram and even Workplace. Considering the global nature of the failure, this is most likely a core DNS error. DNS services are essential to the seamless operation of the Internet, and many-core infrastructures of the Internet are quite outdated.
Although Cloudflare is almost always the central point of failure, the outages are usually local and intermittent, slowing down affecting the website. Anyone trying to connect to any of these services will encounter familiar errors.

Downdetector, a professional website that monitors downtime, shows that the scope of the outage is quite large. Ironically, Facebook’s Antigone Davis was broadcasting live on CNBC, talking about the company’s policies and recent research on social network content, when the service network suddenly went offline and started flashing 5xx server error messages.
Not only is Facebook paralyzed, in fact all of its sister companies are paralyzed. From Instagram, Messenger, Whatsapp, and even Workplace are affected. This is one of the most serious failures in recent history, because Whatsapp is usually unaffected, which shows how highly centralized Facebook is. A central failure point can cause a large area of joint failures.
