Managed to get stoat working over I2P.

Look in to I2P.

We need some more info. What is the server? A dedicated hypervisor? Just a Linux box that Also runs a VM?. If so what software you use to run the VM and containers?

Like I use XCP-NG on one of my servers. It is a level 1 hypervisor which you can manage with a webui.

Not necessarily. A bit of both I would say. My servers can run a few hours on the UPS but bellow a certain threshold it shuts my servers off safely. For most power outages that’s enough to keep things running.

It is and their is already at least one instance.
