For the first few years of Facebook’s existence, we served our users from data centers in a single region in Northern California. As the site grew, we added a second region of data centers in Virginia in 2007, and this year, we launched our third region in Prineville, Oregon.
Our new facility in Prineville marks a shift in our data center strategy. Previously, Facebook leased data center space from other companies. In Prineville, we built the entire data center and servers from the ground up, designing everything in tandem to achieve maximum efficiency.
