Echoes
The internet's physical routes were set by telegraph lines, railroad easements, and telephone switches long before anyone imagined what would travel through them.

60 Hudson Street and the Persistence of Place
There are pneumatic tubes running the full height of a building in lower Manhattan. They were installed in 1930 to carry paper. They're still in use, though not for paper. What they carry now, and why nobody ripped them out, turns out to be the same question.
Technology eras look like clean breaks from a distance. But certain buildings, certain basements, certain stretches of underground duct keep mattering long after the signals they were built for go quiet. A snowstorm in 1888 likely still shapes where the internet is fast in Manhattan. The geometry of that claim starts at 60 Hudson Street.

The Ocean Floor
In 1854, a U.S. Navy oceanographer named Matthew Fontaine Maury identified an undersea corridor between Ireland and Newfoundland. He called it the "Telegraph Plateau." The plateau turned out to be a myth. The corridor was not.
Over 95% of intercontinental data still travels by submarine cable, and many of those cables follow routes first surveyed for Victorian telegraph lines. The seabed hasn't moved. The hazards haven't relocated. Three-quarters of Northern Hemisphere submarine cables pass through Irish waters today, threading the same needle Maury found 170 years ago.
Geography wrote the playbook once. Every generation since has simply retraced it in faster glass.

Why American Fiber Follows the Railroad
Overlay a map of America's long-haul fiber optic backbone onto its Class I railroad network and the two are nearly identical. Same cities, same corridors, same hubs. The engineering explanation is straightforward: cleared ground, existing infrastructure, accessible terrain. But the deeper pull involves legal permissions granted to railroad companies in the 1800s that never expired, never narrowed, and kept drawing each new generation of communication technology into paths laid down for steam locomotives.
The Same Narrow Water
On land, old legal corridors pull new technology into old paths. At sea, geography does the locking. In February 2024, a drifting cargo ship dragged its anchor across the floor of the Red Sea and severed three submarine cables, knocking entire African nations offline. The route those cables followed through the Bab al-Mandab Strait was the same route telegraph cables followed in 1870. The strait hasn't widened.
