Checked isitdownrightnow.com and said Netflix was also down. Any chance these are related?

Earlier quoted context omitted.

WhatsApp is pretty important infrastructure for most of the world

For some egregiously loose definitions of "infrastructure," maybe .

In parts of South America it's used for all sorts of things. Want to know when your bus is arriving? The bus company likely only knows because the driver is WhatsApp'ing them status updates.

Interesting, even some open source sites like: https://fbinfer.com are down but https://glean.software and https://reactjs.org aren't

Anything hosted on Facebook's infrastructure is down. The two sites that you note are up aren't hosted by Facebook.

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

I'm seeing similar DNS errors for many non-Facebook sites.

Looks like HN is being hit pretty hard right now?

I thought Facebook, Instagram and WhatsApp ran on different infrastructure (and they've been trying for a while to align everything)?

How could they all go down at the same time, if they have different teams of engineers running each product separately?

Could anyone with some background (or person familiar with the matter) explain how their system's set up?

Is it just me or HN also feels kinda laggy?

Is this related to the outages from lets encrypt root cert expiring? Probably not since this looks like a DNS issue, but still it's a crazy coincidence that two major internet breaking events happen in the same week
