Any simulator (machine) on the simulator VPN, with the correct
certificates, and with the correct simulator binary can bring up any
region (island/"sim"). Pragmatically, we limit machines to specific
data centers. This is done because adjacent regions chatter back and
forth considerably and there's no sense in sending that traffic across
the country. But 2 seconds in a web tool and you can change the home
colo for a thousand regions. But within a datacenter, regions can and
do migrate between simulators when simulators fail or if a region
repeatedly crashes on the same simulator.

The address move project that I believe you're thinking about was for
changing simulators' IP addresses. That's a bit more touchy.
