Get something like a PiKVM and drop all of the stuff about being very local since you can find a cheaper overall provider elsewhere and use smart hands once a year either for free or still cheaper than picking the local place you can drive to. Even if you do the things in this guide perfectly it'll break/hang/get misconfigured at some point and the PiKVM (or like) lets you remotely hard boot a box instantly without having to drive or open a ticket. It also enables you to easily reinstall the entire OS remotely if you need to.
If your server/device has an IPMI... get a PiKVM (or like) anyways. Not only will you last more than 2 seconds without being hacked but it'll have more functionality and be much faster.
If you're in the US there are lots of places in the Kansas City area that have ridiculously cheap pricing and it's decently centrally located in the country.
I don't want people to think TinyPilot is a bad option but this is where their marketing really grinds my gears. PiKVM and TinyPilot both have preassembled ordering option.
TinyPilot's compare and contrast point of "To exercise the full functionality of PiKVM, users must install a custom circuit board on top of their motherboard and re-route their power supply's ATX pins." is a complete farce (it's not required) and worded in an intentionally scary way (the only reason TinyPilot doesn't have this requirement it doesn't offer the feature while PiKVM does). The "custom circuit board" is literally a PCB that, optionally, allows you to jumper the inline the remote power controls in a way that the normal power buttons still work too rather than rely on ACPI signalling over USB.
It honestly makes my blood boil to see this underhanded approach works so well... the TinyPilot device is good though, as are some other options. Just keep in mind if you opt to go with ACPI only remote power controls via USB things may still go bad if your system hangs/crashes/gets in a weird power state whereas plugging in the wires to the PiKVM will be no different than holding the power button.
