The Internet knits today’s society together, yet most of us aren’t familiar with exactly what comprises “The Cloud”. Last month, NPR’s Terry Gross interviewed Andrew Blum, the author of a new book, Tubes, A Journey to the Center of the Internet. The book explores the hardware infrastructure that instantly transports data across the globe. Ms. Gross asks the questions that any layperson would ask, and the author replies with amusing stories of his adventures inside the Internet’s data centers, points of presence, repeater huts, and cross-connect centers.

Fiberoptic cable often shares the conduit, cable trays, and trenches where 100-year old lead-sheathed oil-impregnated paper-insulated copper cable still resides.
