No matter how careful you are adding automated tests and test to verify those tests have run OK, and making them fail safe (fail with a warning in this case) where possible, it will always soon get to a point that there needs to be a manual “have we seen the everything is OK message recently?” or similar is by far more efficient than adding another tests to send a warning when the last layer of tests has failed.
