Brookings, SD Internet Speeds — Measured 2024
Real speed tests run in Brookings County, South Dakota during 2024 recorded a median download of 85.1 Mbps, upload of 17.4 Mbps and latency of 35.8 ms, across 2,516 measurements. That is 1.0× the US median and places it #1,215 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 Brookings came in below 85.1 Mbps and half above. The slower quarter of connections measured under 39.9 Mbps, while the faster quarter exceeded 127.7 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 85.1 Mbps down and 17.4 Mbps up, a typical household here can handle HD streaming and video calls, though simultaneous heavy use may compete for bandwidth. Latency of 35.8 ms is acceptable for most real-time use.
