Network latency — the globe measured from a command prompt

The claim

“Inter-city distances are invented to fit the globe; you can’t measure them yourself.”

What is measured

A Sydney–Santiago round trip returns faster than light could even cross the ~2× longer flat-Earth map distance. Its timing fits only the ~11,300 km great-circle path on a globe.

What would show this is wrong

a measured ping below the great-circle light-floor, or one matching flat-Earth map distances instead.

Sources

  1. Speed of light in fiber & network latency. Light in optical fiber travels at ~200,000 km/s (refractive index ~1.47), so network round-trip times have a hard floor set by great-circle distanc link
  2. The speed-of-light latency floor. The minimum possible round-trip latency between two points is set by their great-circle distance at the speed of light; high-frequency-trading links (Chicag link
  3. Submarine cables vs satellites. Around 99% of intercontinental internet traffic travels through submarine fiber-optic cables; the U.S. FCC found satellites carry about 0.37% of US internatio link
  4. A southern cable that falsifies the flat-Earth map. The South Atlantic Cable System (SACS) links Sangano, Angola to Fortaleza, Brazil in 6,165 km at ~63 ms round-trip — close to the ~5,740 k link
