Earlier quoted context omitted.

If that VPS is on DO they're down too cause of CF. Or if you set the resolver on your VPS to 1.1.1.1 that's also down.

Why are digital ocean VPSes down due to a Cloudflare outage? Hoping for a clarifying post mortem...

My Digital Ocean load balancer went down. I think there's probably some internal routing? Would be interested to understand more.

Oopsie Daisy half the internet goes down

Eggs and baskets etc etc

Good DNS practice (at least when I did system admin 10 years ago) was ALWAYS having a secondary at some other location/network. Why do we just put some info in Cloudflare and call it good these days?

Is there a status page for HN?

EDIT: Yes: https://twitter.com/HNStatus HN is so reliable that’s it’s almost never needed one. I’m extremely curious how HN survived this; almost positive they used cloudflare at one point. I think the official status page is @hnstatus on Twitter, or something like that.

HN is reliable until AWS Route53 goes down :).

Our TPU management page is also down: https://www.tensorfork.com/tpus Seems cloudflare took out a good chunk of the internet temporarily. Doesn’t HN use cloudflare? Why did it survive? (I haven’t looked for about a year, but I seem to remember HN being proxied behind CF at one point.)

It doesn't look like it does. HN's IP space belongs to "M5 Computer Security", and their DNS nameservers are on "awsdns". Nothing there to suggest CF.

It really defies the original vision of the internet to have so many services depend on a single company. Almost every news site I was reading dropped off at once. I thought for a second that I lost internet in my own house.

Yes its really odd that core backbone providers can go down and everything works like its supposed to. Even trans-pacific cables can be cut and things will usually work with only increased latency. But there is not much redundancy for many companies at this layer; having redundant DNS providers is I'm sure possible but not something we think about very often, and of course many of the sites that are down are dependin…

I imagine most people would never expect something like this to happen, so having a fallback option when Cloudflare has a huge interruption of service like this is just unthinkable.

Lol, talk about timing. I'm currently working on a TLS library and was pulling my hair out trying to figure out why tests against CF sites suddenly failed. Can't even ask my cohorts on Discord because they are behind CF, too!
