Many people run rented servers with capacity to spare.

Nice. Where is power port on a hooker? Eh, nevermind.

I use photovoltaics, but not insular blackstart-capable battery buffered so when the grid is down I also have no power. Next year, though. Seems it’s 2000 EUR minimum.

Yes, that’s called StarLink. Definitely a good option, if you make your own power.

And run 2 or 3 uplinks to different ISPs so that you’re never offline.
