The DNS lost angle is techno-baloney. DNS part is working, in fact FB runs its own nameservers. Separately, FB domain name registration doesn’t expire until 2030.
Whatever is going on, is the typical “too many moving parts under the hood, and something got mixed up.”
I’ve been out of network management for 22 years, but every destination needs a root server entry, and that seems to be gone. Whether an organization has its own DNS server is immaterial.

Do you know what a border gateway router is? That is the network of routers across the world that directs data packets from the origin to the destination. The outage has been caused by all of the routes that Facebook uses suddenly deleted from the network. Therefore, the Facebook origin servers naming is useless if all the Gateway Routers at Verizon, AT&T, Level 3, etc., don't know how to deliver the data packets.
I was once one of those Verizon Techs before I retired. We had bays and bays of Border Gateway Routers at the South East Regional Junction facility.
