The security at NY4 bears this out. To get from the parking lot to a spot where you could touch one of the servers you’d have to go through five checkpoints. One of them is a so-called man trap with two automatic steel doors that never open at the same time. Your palm print is required twice in addition to your PIN code. A wall of video monitors captures every nook and cranny of the 338,000-square-foot building.
Once you’re in, the space is enveloped by a rush of white noise from the thousands of computer fans whirring away to keep the servers cool. To help maintain the temperature, the ceiling is 45 feet high, roughly four stories up. It’s barely visible—not just because of its height, but also thanks to all of the suspended trays of cables and cooling ducts running overhead. All this goes toward one statistic: Equinix says in its annual filing that it kept its facilities up and running 99.9999 percent of the time in 2015.
