Yeah. I'll try setting up a better monitoring / alerting to notice
issues like this more promptly ... it's a bit tough, because IIRC the
gap 2021-10-22 - 2022-02-10 was due to the tests running, but getting
stuck for some reason. So it's not like the machine was off.
I wonder if it'd make sense to have some simple & optional alerting
based on how long ago the machine reported the last result. Send e-mail
if there was no report for a month or so would be enough.

It's actually a bit worse than that, because both animals are on the
same machine. So avocet gets "stuck" -> trilobite is stuck too.
