Re: I've often wondered
Even in a cooler area, you still can't depend on ambient cooling, you still need the fans and chillers and evaporation stacks. (As much as my customers with 5 broken fans expect my datacenter to cool their chips for them in a locked box in a locked up rack).
A largest factor is cost of power. And where power is cheap is high-density low-income areas. Not out in the hinterlands. High-density areas are typically in the hotter areas.
They've done the math for both in and out, they would go wherever they get the most return.
