correct, if you run a dedicated monitoring system for a handful of targets. If you run a SaaS or a very large monitoring system for a large corporation, this doesn't fly anymore. There is simply no moment available to be down. There is always overlap with some system.

To an extent.
A monitoring system that is unreliable risks losing trust. Monitoring systems that aren't trusted tend to be ripped out or ignored.
If it is down too often, people will constantly question whether its silence is an indicator of health.
If it triggers too many false alarms, people will constantly question whether an alarm indicates a real problem. If it gets bad enough, they might start ignoring them.
Only slightly; they just need to have an extremely low likelihood of going down at the same time.
It’s okay if your monitoring is down sporadically, just as long as it doesn’t overlap with the device under test also going down unexpectedly.
