Explaining Facebook’s global outage, Facebook’s Chief Technology Officer John Graham Cumming said that several social media handles, including Facebook, disappeared from the Internet in the wake of the BGP update.

What is the reason for the BGP update? If you want to know about BGP, the first thing you need to know is what DNS is. Simply put, DNS is an Internet phone book. This converter is used to assign an accurate IP address to any web domain on the Internet.

The first DNS error appeared on Facebook on Monday. It means that facebook.com profile could not be seen. From the outside I didn’t think the problem was too big. Nobody understood. The Facebook ecosystem will collapse in an instant.
