Let's hope it's permanent.

Of all the big tech companies Facebook is the only one where it can completely disappear overnight and my life would be completely unaffected (or possibly improved by not having to explain to people I don't use facebook, please email or text me your invitations rather than use messenger). If Google, Amazon, Netflix, Apple disappeared the story would be completely different.

disappearance of FB might not impact you, but India runs on WhatsApp.

This sounds like something that might have been done with security in mind. Although generally speaking, remote hands don't have to be elite hackors.

Have you ever tried to remotely troubleshoot THROUGH another person?!

Yes. Depending on the person, it can either go extremely well or extremely poorly. Getting someone else to point a camera at the screen helps.

It isn't just DNS. If you happen to have cached entries, the site is returning errors as well.

Presumably the DNS being down also wreaks havoc in their internal infrastructure as services can no longer resolve each other's names.

I wonder if Facebook has circular 'boot' dependencies on their microservices or something? I.e. they can't restart stuff now when everything is down.

For Facebook and WhatsApp it looks like a DNS issue, name resolution fails with SERVFAIL: $ dig facebook.com ; > DiG 9.16.21 > facebook.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER

Even Google's 8.8.8.8 DNS server says can't find, SERVFAIL.
