Earlier quoted context omitted.

Most sites set the absolute minimum TTL for every record, for no reason. There’s a lot less caching than you’re thinking.

Eh, what? There are many good reasons to have low TTL DNS...this exact outage being one of them. Update your records to go direct to your servers, and not through Cloudflare and bam you’re back up. Doesn’t work if your TTL is 86400

Doesn't help as cloudflare wants you to host their name servers with them, so you can't flip any records if the DNS itself is in trouble, like it is now

And changing DNS servers often takes many hours (or days, if .net is involved apparently)

It's back now (at least for me).

Seems like it’s back right?

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.)

HN allegedly still runs on one machine running a single-threaded Lisp webserver.

The status page is now showing degraded performance for the Cloudflare API and Recursive DNS.

We can't keep going on like this. The vulnerability of centralised internet infrastructure is a huge problem for everyone. Somebody, somewhere, really ought to sort it all out

Be the change you want to see in the world :) There are no somebodys somewheres.

One question is how to do DDoS protection without somebody like Cloudflare. Some new protocol for edge caching, perhaps?

Yesterday I noticed most of their lava lamps are out (which generate random bits). Perhaps these are a critical component. https://photos.app.goo.gl/g6eR8V2PSY3EVjCLA

I'm sure you were joking but they actually are: https://blog.cloudflare.com/lavarand-in-production-the-nitty...

Hopefully with this outage Cloudflare will finally provide non-Enterprise plans a CNAME record, allowing us to quickly bypass Cloudflare.

Looks like it's resolved -- we're coming back up at Repl.it.

I don't use Cloudflare, but I do notice Cloudflare services being down. Right now, I can't get to my own website (hosted on DigitalOcean, not through Cloudflare), but Oh Dear claims it's up. So I suspect that the problem is closer to me than it is to DigitalOcean (or Cloudflare).

DO might use 1.1.1.1 (or Argon even) for routing between some of their PoPs

Could be. Things are back now, but I was very surprised that a Cloudflare outage makes it impossible for me to get to my Kubernetes API server.

Hidden dependency revealed.
