It's never DNS. It's the bonehead that messed up DNS.

Facebook looks like a dns issue - I get SERVFAIL from quad 9s when attempting an nslookup. Cloudflare has no records, Google dns doesn?t know, opendns makes an exaggerated shrug gesture and looks worried

Here?s a sysadmin poem:

It?s not DNS
There is no way it?s DNS
It was DNS
