Earlier quoted context omitted.
You need on the order of 15 permanent onsite employees to run a datacenter; 5 each for 24/7 coverage of security, building maintenance, and tech. You probably don't really need 24/7 onsite for building maintenance or tech. Traveling employees or (probably traveling) contractors can handle projects that exceed the local scope. Should be able to locally source security and building maintenance, if the pay is good. Thes…
I don't consider 30 minutes away from town the "boonies", that's more like a normal commute. The boonies would be like a 3 hour drive in the Sonora desert.
You want your datacenter to be in reach of interstate highways (rail might be nice, too), two electrical substations [1], and close to fiber that's already run. That restricts your available boonies, but there's still lots outside of the east coast.
[1] yes, you'll have onsite generation, and yes, you might plan to run from onsite generation most of the time, but you still want to have the option for utility power, and it's nice to have two substations to get more uptime, subject to more transfer switch complexity.
