I wonder what limitations exist for storing server farms in a satellite or in international waters. Or in weather balloons and UAV's...a la Project Loon and whatever Facebook did with those ever flying UAV's
Even if you locate your server farm outwith unfriendly jurisdiction, you still need to connect it to the rest of the world, and it's difficult to do that without engaging the services of a company that is susceptible to influence by an unfriendly government. You're also susceptible to being effectively (if not literally) sanctioned via the financial system.
Sidestepping jurisdictional issues altogether by operating entirely virtually is a better bet right now (c.f. ASICminer).
