That's probably just because there's not much demand for it, not because it's difficult.

There are mines with plenty of space in them, and heat removal can be done with water cooling. But who is going to pay 50% more for that when it isn't needed 99.99% of the time?

Or when the same thing can be accomplished by putting nothing in a mine, but an approach as simple as having geographical diversity by paying for some 'normal' colo in Hillsboro, and more normal colo in northern VA on the other side of the continent, and duplicating your stuff between two facilities. Weird underground datacenters aren't exactly known for having a large number of competing on-net carriers.

Huh? The ones I know of have plenty of connectivity. The real issue is your first, that people prefer to just put their stuff in two countries over paying premium for having their servers under ground.

		Your definition of connectivity may not be the same as mine, I'm referring to the number of facilities based carriers and those who ride on top of them you can get at major sites in Hillsboro. Facilities with peeringdb pages that have tons of on net carriers. Is there even an underground bunker colo that's big enough to rate its own peeringdb facility page?
