It's a 333,400-foot facility with tens of thousands of servers--Facebook doesn't like to say precisely how many--yet it's operated by a grand total of 55 people, about half of whom are involved in its security. I took photos of servers, the extensive space devoted to cooling them, the gnome garden (who knew Facebook had a gnome garden?), and more."
