I think we want to start with web hosting.

Small servers (SBCs, probably Rock-pro or similar) 10G fiber connections, the basement of an old farmhouse.

We wouldn't have 5 9s, but we'd have at least one 9. We wouldn't have the juice to host the next Youtube, but our peertube servers are doing just fine, etc. etc. etc.

I've been working in and around datacenters for 16 years, some of the other folks involved in this were running Dial Up ISPs off t1 lines at a time when that made sense. I'm confident that not only could we start a DC, but that we could make it both sustainable and maybe even profitable, while also, you know, not hating ourselves.
