Right, but they didn't recover speedily. To have the cluster in such a state for so long sounds like poor monitoring to me because this can knowingly interfere with an election later.

The health check said it was ok. How would they know it needed to be recovered?

The fault was the bad health check. Not the process.

They only just clarified that monitoring was in place and they were reporting as healthy. See the comments above.
