EVER wondered what happens to your Google searches every time you hit the "I'm Feeling Lucky" button on the search site's front page?

Google did something unprecedented recently, and took its Street View cameras inside one of its own top-secret data centres.

The huge building in North Carolina is crammed full of thousands of specially made computers.
