I haven't worked for a FAANG but it would be unthinkable that FB does not have backup measures in place for communications entirely outside of Facebook.
Hmm well I mean for key people, ops and so on.
Not for every employee.
Only a few people need that type of access, and they should have it ready. They need to bring more people there should be an easy way to do it.
Maybe the internal FB Messenger app has a slide button to switch to the backup network for those in need.

Having worked for 2 FAANG companies, I can tell you most core services like which FB Messenger would be using internal database services and relying on those which would be ineffective in a case like this as it would not work and the engineering cost to design them to support an external database would be a lot more than just paying for like 5 different external backup products for your SRE team.
