I've been to a datacenter that had part of Wikipedia in it in Dulles, VA. It's definitely not a basement, it's one of the coolest places I've ever been.
The company I worked for was decommissioning a server rack and they needed some warm bodies to unhook cables, so they let some non-sysadmins go in to help out. Security was super tight, but once you got in there it was a nerd's wet dream: Whiteboards everywhere, weird foreign snacks and energy drinks, dim lighting with sick red neon trim.
I also got to keep all the Ethernet cables I wanted which was pretty sweet.
I do want to point out that a free culture kiss is more intimate than it initially seems. With proprietary kisses, you never really own the kiss. It is not your kiss, rather you're allowed to hold on to the kiss until its giver decides to take it away again.
Only with a free culture kiss the kiss is really yours.
