A Down Detector for Down Detector's Down Detector

"Further investigation quickly established what it was that had happened. A meteorite had knocked a large hole in the ship. The ship had not previously detected this because the meteorite had neatly knocked out that part of the ship's processing equipment which was supposed to detect if the ship had been hit by a meteorite."

The book ("Mostly harmless") and especially the beginning of the first chapter is worth reading as it describes how the automated systems of the space ship try to resolve the situation.

As per usual, all new is something old, well-forgotten.

didnt check past that

This one looks like it's behind a CDN, at least

It would be interesting to see just how small this whole thing could be; I bet it could be made into a <500MB sdcard image for a RaspberryPi4/2GB that simply updates a static css out of (say) cron and serves a surprising number of HN requests.

With all of this redundancy, there is no way it could fail! /s
