⚙ Under the hood

Interactive 2D map of how fast a message really travels between world cities: fiber with route inefficiency and refractive index, a low-Earth-orbit laser relay, and the speed-of-light limit straight through the Earth, with a live latency-versus-distance graph and slow-motion packets.
