Sussex, DE Internet Speeds — Measured 2024
Real speed tests run in Sussex County, Delaware during 2024 recorded a median download of 114.2 Mbps, upload of 21.6 Mbps and latency of 13.4 ms, across 12,877 measurements. That is 1.3× the US median and places it #169 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 Sussex came in below 114.2 Mbps and half above. The slower quarter of connections measured under 47.0 Mbps, while the faster quarter exceeded 262.7 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 114.2 Mbps down and 21.6 Mbps up, a typical household here can comfortably run several 4K streams alongside video calls. Latency of 13.4 ms is excellent for gaming and real-time calls.
