How The Internet's Physical Cables Decide Your Latency
We explore the physical layer of internet infrastructure, specifically how undersea cable geography and fiber optic attenuation dictate global latency. Lucas and Luna break down why your data takes a specific path through the Atlantic, the role of submarine repeaters, and how network engineers optimize routing based on physical distance rather than just logical hops. We examine the real-world constraints of signal degradation and how modern engineering mitigates these issues to keep cloud performance consistent for businesses in September 2026.
