Our monitoring went silent for 25 hours and production was perfectly healthy
Two scheduled canaries stopped running because of a billing event, not a bug. The jobs died two seconds in with zero steps recorded, the status page said everything was operational, and the only honest message was hidden in a check annotation. A monitor that stops and a system with nothing to report produce the same artifact, which is silence. Here is what we found, what we moved, and the blind spot we deliberately did not close.
