Cheap land is nice, but it's not the only concern. Data centres make a lot more money per square foot than things like farming, after all.

You also want cheap, reliable power. Ideally eco-friendly. And you want backbone connectivity, of course. Local suppliers who know the construction and maintenance needs of a data centre. No earthquakes, hurricanes, wildfires, flooding, or tornadoes. A local government that won't tax you too much, and that won't get upset when you employ very few people.
