During that time the device was mining on pool 172.31.26.43:4444 and one of the blocks was 847711, which is indeed the block from 2024-06-13 07:29:26. So, obviously they are testing on a productive environment.
Why not using produced devices in a sliding window principle for testing and mining? Has anyone seen this in other production environments?
Here is a small part of my log:
