Plymouth, IA Internet Speeds — Measured 2024
Real speed tests run in Plymouth County, Iowa during 2024 recorded a median download of 56.9 Mbps, upload of 10.7 Mbps and latency of 30.1 ms, across 1,417 measurements. That is 0.7× the US median and places it #1,880 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 Plymouth came in below 56.9 Mbps and half above. The slower quarter of connections measured under 29.8 Mbps, while the faster quarter exceeded 96.5 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 56.9 Mbps down and 10.7 Mbps up, a typical household here can handle HD streaming and video calls, though simultaneous heavy use may compete for bandwidth. Latency of 30.1 ms is acceptable for most real-time use.
