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

Also I think I triggered a nice error log in domaintools just now. https://whois.domaintools.com/downdetectorsdowndetectorsdown...
From there, the "who's watching who?" can become mathematically interesting.
Since down detectors serve to detect failures of centralized (and decentralized systems) the idea would be to at least get that right: a distributed system to detect outages.
You basically run detectors that heartbeat each others. Just a few suffice.
Once you start to see clusters of detectors go silent, you can assume things are falling apart, which is fine so long as a few remain.
Self healing also helps to make the web of nodes resilient to inevitable infrastructure failures.
Looks like it's hosted in London?
