Actually that is exactly what I'm trying to do. Sometimes you want to run you application on you own metal. Actually I have access to it 90% of the time. So hoped there might be some solution to it.

Basically what I was thinking of what might be a solution for a specific problem: 1. Rdp or ssh doesn't work - server hangs. Restart it somehow remotely. It would be enough if some device was able to press the power.

2. Router hangs. Maybe I could just restart it through remote power supply which is connected to a second internet connection through LTE for example.

Of course if something very terrible happens like a fire you need be at the place. But I think most of the problems can be solved with just restarting the devices. The tricky part is to do it remotely.

Yes, just have a second Internet connection and three (or more) remote-controlled power distribution units. Double AC. Time slot planned for the yearly AC maintenance.

Each modem/router on its own PDU, daisy-chained to a shared last-chance PDU.

Thanks! Will try that path : )
