In our evaluation of over 160 million speed tests, South Dakota demonstrated network responsiveness with a median round-trip latency of 28.44 ms alongside median download speeds reaching 173.6 Mbps and upload speeds of 30.5 Mbps. Real-world network performance reveals noticeable variations between leading urban corridors and surrounding communities.
