As my wife just pointed out, it's cheaper than a lot of houses in Palo Alto and way cooler!

And much bigger too!

Great for data centers?

The article implies that it is fairly warm in the tunnels, so unless the data center can be made cool...

They were running generators down there, so there must be cooling available. I guess they've just left it off to save money while there's no tenant.
