There it is. The stutter. The jitter. It is the sound of a traffic jam happening at 600 miles per second. It is a buffer overflowing in a rusting server rack in Omaha; it is a fiber optic cable bending slightly too sharp under the Atlantic; it is the micro-second hesitation of a router deciding which path is the lesser of two evils.
