Oh wow that's fantastic! Are you referring to https://fcix.net/ ? Thanks so much for the tip. Do you know how much it costs to grab a dedicated box in the HE Fremont facility?
So they don't do dedicated boxes (sadly), they rent by the rack (including 1gb of transit + 15A power). https://he.net/colocation.html has the info. If you just want a dedicated box that isn't drawing a lot of power I've probably got some room in my rack and we can chat (and I imagine some of the other BGP for fun group folks are in similar positions).
It's very easy to run out of cumulative watts of grid power feed, cooling capacity and generator/UPS/power backup capacity in a facility before you run out of floor space in a datacenter.
Even with what is now a "small" 5kW thermal power budget per 44U cabinet, measuring 24 inches wide x 48 inches deep, you can easily exceed that 5kW long before you physically fill the cabinet with servers.
