Sightseeing There are a few well-known locations that people tend to go to when they want to "see the internet" in New York. Of course, there are plenty of not-so-famous buildings in Manhattan that store lots of data and connect networks to each other. Identifying these buildings when looking on the street is not always easy, but one telltale sign is to look for signs of ventilation and cooling systems. Alternatively, look for windows, or more accurately, the absence of them. (Note: on much larger buildings, in particular skyscrapers, vents also could just be a sign of a mechanical floor, the centralized space dedicated to maintaining utility needs for the entire building.) New infrastructures have a tendency to inherit the homes of past infrastructures, and the internet is no exception. Many of the major internet exchanges and data centers of Manhattan are in buildings that used to be telegraph switches, telephone company headquarters, and other industrial spaces. While this is by no means an exhaustive list, these are a few interesting starting points from which you can start looking for cable markings, cameras, or other signs of internet infrastructure.
