Andrew Blum’s journey to the center of the Internet, as he calls it, begins when a squirrel nibbles the wires of his house, shutting his online access of. This event sparks a years-long journey of curiosity to figure out how the wires all connect, and how data flows through the physical space of the world.
In Tubes: A Journey to the Center of the Internet, Blum brings us along with him. It’s a pretty fascinating ride, if a bit technical at times, as he researches, investigates, and visits some of the main hubs of the dispersed Internet, from data centers to undersea cables to spaces below buildings in urban centers to isolated rural places — all forging different kinds of connection so that when I hit “publish” on this blog post and you click to read what I wrote, the data flows rather seamlessly (or so it appears) through fibers, wires, and yes, tubes of light.
There are moments where Blum geeks out a bit too much for my tastes, but I understand why he goes into such descriptions about routers, packets and fibers. What I was more interested in is how he frames the flow of information with the physical aspects of the world — the way we can imagine data moving along the contours of our Earth, and the ways in which those same contours provide barriers of access, too.
Overall, though, Tubes gives the reader a fuller sense of the digital world — sparking some appreciation for the original design of a distributed networked space and for the rather fragile elements that make up what we mostly take for granted. Some hubs are monumentally important, and yet, as Blum describes them, neither as secure as one would expect nor as reliable as they could be.
I really appreciated these final thoughts of Blum, who seeks to humanize his research, and ground it in the world we live in, not the virtual one we imagine when we use our technology.
“What I understood when I arrived home was that the Internet wasn’t a physical world or a virtual world, but a human world. The Internet’s physical infrastructure has many centers, but from a certain vantage point there is really only one: You. Me. The lowercase i. Wherever I am, and wherever you are.”
