Nice! Who doesn’t like a good recursion? Fingers crossed that the down detector for down detector won’t be down, when down detector might be down
kijin•1h ago
Use the original down detector to monitor the down detector for down detector for down detector. Complete the circle!

Yeah we had a good laugh when Downdetector was down during the Cloudflare outage yesterday. So this is appropriate. +1

Ah, now we know that the answer to "who watches the watchers?" is "@gusowen". :D
gblargg•1h ago
Would it be a good idea to have a second instance of this watching the first one? /s

Thank you for your service! Now, for an even bigger challenge: since it seems the increased demand for the Cloudflare status page brought down Amazon CloudFront for a bit as well, build a new CDN capable of handling that load as well...
carstenhag•48m ago
Do you need a CDN for a static html, no images? I would guess no, even if you.are being bombarded with requests

But we need another one to detect whether yours is still up.

It's downdetectorsdown all the way down.

Given enough of them, some fraction will always be down. It would be helpful if we had a site that could track that ratio.

Downdetection can be thought of as a directed graph, or digraph*.

From there, the "who's watching who?" can become mathematically interesting.

here's a page that monitors that page: https://onlineornot.com/website-down-checker?requestId=jCfaD...

Looks like it's hosted in London?

ricq•1h ago
Is it hosted on Cloudflare?

As a European solo developer, I’ve switched entirely to European alternatives for all my infrastructure since the beginning of the year.

Cloudflare > Bunny.net

AWS > Hetzner

Business email > Infomaniak

Not a single client site has experienced downtime, and it feels great to finally decouple from U.S. services.

> Bunny.net

Ah yes, the place for RabbitMQ endpoints.

buildfocus•16m ago
I've done something similar, it's worth noting Scaleway in the same space, for people looking for an AWS replacement more like managed services (equivalents to fargate/lambda/sqs/s3/etc) instead of just bare instance hosting.

Sup dawg, I heard you like down detectors.
