The data centres that run the internet are kept pretty quiet, and for good reason: forget cyberattacks, a few well-placed hatchet swings could kill Snapchat worldwide. But photographer Peter Garritano recently gained access to some of the exchanges and colocation centres that underpin the internet, and brought back these photos.
The facilities he visited aren't the giant data centres that power the likes of Google or Facebook; instead, they're the important internet infrastructure you've probably never heard of: peering exchanges that trade data between telecom companies' back-end networks, or the domain name servers that make sense of the internet.
