We have now improved the speed of loading and extraction of downtimes.

No - there wasn't bug in our code on Thu morning and the wall didn't deserve the words. It was an actual downtime that we detected 11 minutes before Let's Encrypt.

Just to clarify - it doesn't monitor your certs. It actually measures the performance of the Let's Encrypt CA.

We purchased 400 domain names to get round rate limits so we can request 80,000 certs / week and measure the uptime and latency.

You don't necessarily need the aircraft to emit any signals, you may be able to detect changes in the background RF emissions reflected or distorted by the aircraft. It would have to be enormously CPU expensive but if you can correlate changes in tens or hundreds of frequencies, I can imagine it could be done.
