Carbon, MT Internet Speeds — Measured 2024
Real speed tests run in Carbon County, Montana during 2024 recorded a median download of 23.0 Mbps, upload of 5.8 Mbps and latency of 49.6 ms, across 592 measurements. That is 0.3× the US median and places it #2,342 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 Carbon came in below 23.0 Mbps and half above. The slower quarter of connections measured under 11.3 Mbps, while the faster quarter exceeded 57.3 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 23.0 Mbps down and 5.8 Mbps up, a typical household here can manage standard streaming and browsing, but will feel the limits with multiple users or large uploads. Latency of 49.6 ms is high enough that video calls and gaming may feel laggy.
