I'm glad someone brought up the NSA datacentre. I was thinking is there any connection to this? How far is it to being finished? Is that public knowledge/possible to find out?

It wouldn't warrant this amount of data, which I would expect is pretty small in comparison to the capabilities of this NSA datacentre?

Probably too far fetched an idea...
