Today I was very fortunate to have gotten a tour of Facebook’s new datacenter up in Prineville, Oregon (map). This datacenter is the most energy efficient in the world and only a handful of press got a look. We’ll have a video up after editing it, but here’s a look at the datacenter in photos. I shot all of these photos on an unmodified iPhone 4 with Instagram, that just got an update today. For the panoramic photos I was using Occipital’s 360 app.
