This is something that even larger corps struggle with. My old company would buy some other company, lay off a bunch of people, others would quit, and then it was shocked Pikachu faces all around when That One Thing stopped working in an office they turned into a ghost town and, well, no, nobody was going to be there until Monday morning to power cycle etc. True lights out/OOB reachability is WORK. And there’s always going to be a SPOF somewhere that requires hands on-site.

Do what you can, when you can. And thank you for all that y’all have done so far.
