San Bernardino, CA Internet Speeds — Measured 2024
Real speed tests run in San Bernardino County, California during 2024 recorded a median download of 84.0 Mbps, upload of 12.7 Mbps and latency of 11.7 ms, across 204,272 measurements. That is 1.0× the US median and places it #1,247 of 2,425 US counties.
What these numbers mean here
The median is the typical connection, not the best one available. Half the tests in San Bernardino came in below 84.0 Mbps and half above. The slower quarter of connections measured under 24.1 Mbps, while the faster quarter exceeded 215.1 Mbps — a spread that usually reflects a mix of fibre, cable and older DSL lines in the same area rather than one uniform service level.
At 84.0 Mbps down and 12.7 Mbps up, a typical household here can handle HD streaming and video calls, though simultaneous heavy use may compete for bandwidth. Latency of 11.7 ms is excellent for gaming and real-time calls.
