Someone save a risky release for 9am on a Monday morning? Decided Friday afternoon was too risky?

0830 actually :/ But to be fair... seems like it was a good call to not do it Friday night :D

If they chose 8:30, then it must have been really risky! ;)

Nothing of value was lost

I get that this in jest, but a lot of people rely on Whatsapp and FB Messenger for messaging.

There are plenty of ways to communicate with friends and family. If Facebook is down long enough, many people will just move to something else. (And I hope they do)

Funny enough, I went to https://www.isitdownrightnow.com/ to check if Facebook is down, and isitdownrightnow is down itself... probably from the massive number requests coming to check if Facebook is down

https://downdetector.com/ seems to be working for me at least.

Earlier quoted context omitted.

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.

Internal services using public dns records?

Doesn't seem too clever that Facebook's NS servers are a.ns.facebook.com, b.ns.facebook.com etc. IIRC that kind of setup requires some glue records.

If you mean because the name servers are in the same zone, this is very common. When an NS is returned for a zone, you also get an “additional” A and AAAA to resolve the NS name. It’s called glue.

    dig NS example.com
    ; ANSWER
    example.com. NS ns1.example.com.
    ; ADDITIONAL
    ns1.example.com. A 1.2.3.4
Edit: I didn’t see your glue comment when I wrote this.
