Facebook announced last night that it now has more than 300 million active users, meaning the social network has been adding users at an average rate of 670,000 per day. Most of those users are uploading photos and videos, which requires a lot of storage and computing assets.
That's why Facebook has been aggressively expanding its infrastructure by leasing wholesale data center space from DuPont Fabros Technology (DFT) in Virginia and Digital Realty Trust in California. Here's a look at some of our coverage of the growth of Facebook's data center infrastructure:
