Manhattan's hidden hubs of global internet infrastructure, in pictures (22pics)

 Quietly tucked away in a few unassuming buildings in lower Manhattan, massive flows of data pulse through some of the world's largest hubs of global internet infrastructure.
 60 Hudson st, originally built as Western Union's headquarters in 1930, is among such facilities dotted throughout New York captured in a fascinating photo project by Peter Garritano.
 Construction begins on newly leased floor space at 111 8th avenue.
 Biometric mantraps (double locking doors) are common security protections.
 Conduit carrying lines of power, fiber, and control cables enters a room where backup power systems are connected.
 A network operations center (NOC) where a facility is monitored and controlled.
 Fiber optic cables enter and exit carrier hotels through underground vaults. Some of these cables run local connections, others are on their way to eventually cross the Atlantic.
 In a sub-basement, redundant utility equipment and diesel fuel are stored for disaster recovery.
 An electrical substation transforms incoming voltage and distributes power through a building.
 20-cylinder diesel engines kick on to keep systems running if primary utilities fail.
 Fans move heat exhaust off the roof at 60 Hudson street.

 New higher capacity fiber optic cables are fitted onto a rack, replacing slower copper cabling.

 Electrical switches transfer and distribute power
Raised floors are commonly used to manage wiring and channel cool air ducts directly to server arrays.
 Yellow cables indicate fiber optic lines which carry data encoded as pulses of laser light along a strand of silicon glass. The grey wires are generally lower bandwidth copper cables.
Servers racks inside a peering exchange at 85 10th ave, where large networks exchange traffic with others when a mutual benefit exists.
Ceiling tiles removed for maintenance reveal various conduit, both fiber cabling and utility lines.
A customer's servers are installed in vacant space on a rack at 325 Hudson.
A floor of open racks is used for servers that don't require the additional security of locking cabinets or wire cages.
Build out begins on a floor that will become colocated space.
