If the node is reachable, but nothing is writable, I guess auditing will lead to suspension and disqualification - but not within hours, it will take some time.
Anyway, I strongly advise to install an alerting service, which will update you a) on success statistics as well as b) almost immediately, if an error occurs. I strongly belief, docker logs would have been written anyway (in the RAM?), so that the script would have been alerted you. Pls check it out here:
