You're looking at Apple's superhuge data center. It's where iCloud and Siri live. The company is now putting the finishing touches on a new center. Wired went to check it out. Wired was able to spot some interesting physical details of the 20,000 square foot "tactical data center".
This 11-room facility seems to have a few extra security measures. It includes "man traps," meaning that visitors will have to walk through two sets of security doors to get inside, and it's bordered by its own 8-foot chain-link fence.
Whatever it is, security is super high. Just what do they have planned inside? Wired quotes one networking wiz who speculates that the giant box is a way for other companies to securely plug into Apple's online goods without touching its internal network. Or it could be housing Apple secrets and future products? No one knows for now. [Wired]
