That’s kind of the point tho, nobody has the time to bear the responsibility alone while living a life. Would it be feasible to set up a team? Similar to mods, a group of maintainers could share the burden. I’m not trying to dump this directly on you personally, just entertaining the idea.
A “selfhosted” community server would be an incredibly cool thing to accomplish in my opinion. There are lots of knowledgeable folks here with years/decades of experience in hosting, it would be awesome if a group of them created an instance, collaboratively, so they could support eachother. It would provide a peace of mind for others that a bunch of competent minds are guarding their accounts, communities and user data.
I thought about spinning up an instance myself when I decided to join the fediverse, but I know my uptime and there is just isn’t enough time in my life right now to properly, securely and reliably manage a public facing service.
Haven’t really tinkered with anything similar to be honest, but it should be doable. Figure out your software stack, find the lowest power consuming platform you can afford with enough performance to meet your needs, then power it with whatever green energy you can get. There are many commercial solutions for solar+battery combination.
My approach would be a raspberry pi, a power bank and a usb solar panel, I’m curious what kind of experience it would provide.
