Real speed tests run in Alamosa County, Colorado during 2024 recorded a median download of 107.7 Mbps, upload of 10.9 Mbps and latency of 16.7 ms, across 821 measurements. That is 1.3× the US median and places it #293 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 Alamosa came in below 107.7 Mbps and half above. The slower quarter of connections measured under 53.6 Mbps, while the faster quarter exceeded 155.5 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 107.7 Mbps down and 10.9 Mbps up, a typical household here can comfortably run several 4K streams alongside video calls. Latency of 16.7 ms is excellent for gaming and real-time calls.
