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

Maybe they tried everything else before that. At first it was working but they couldn't serve responses: https://i.imgur.com/UaCtOiX.png Notice the "2020"

The servers struggle to reply a basic 5xx answer.

Two possibilities:

- the DNS services internally have issues (most likely, as this could explain the snowball effect)

- it could be also a core storage issue and all their VMs are relying on it and so they don't want to block third-party websites and think it will last for a long time, so they prefer to answer nothing for now in the DNS (so it will fail instantly to the client, and drain the application/database servers so they can reboot with less load)

Not just you. It is very laggy on my end too.

I unblocked Facebook right now from my hosts file so I could message someone and couldn't figure out why Facebook failed to load. I tested HN and viola I see that the entire world has sent Facebook requests to 0.0.0.0 lol

You broke it.

I didn't receive expected WhatsApp messages and am only now realizing there's no indication within the app that there is even a problem. It only becomes (somewhat) apparent when sending a message never gets a single check mark. Not a graceful failure for the user view.

Earlier quoted context omitted.

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

A lot of people, out of habit, rely on high fructose corn syrup for calories.

My mother uses FB/Messenger to talk to her children and grandchildren.

My extended family uses FB to share info about events.

This, and other pedantic activities are really common around the world.

Don't reduce the material reality a situation to a meme that that represents a personalized view.

I would like that say that after my "burn it down" comments on another Facebook related post that I had nothing to do with this.

With the Facebook properties down, the rest of the internet will have a significant increase in usage.
