Analysis of 42m broadband speed tests reveals the fastest and slowest places in America

  • New data extracted and compiled by Cable from over 42 million US speed tests reveals the difference in the average broadband speed across the United States
  • Rhode Island ranks as America's fastest state with an average speed measured at 36.69Mbps, with Montana coming in last with an average speed of 10.94Mbps
  • The fastest place in America is Washington VA, with a download speed of 210.19Mbps, with marked contrasts between cities across America, even those in the same state
  • In contrast the slowest place in America is Southerly North Slope Bo AK, with a download speed of 0.28Mbps

Tuesday 10 October 2017:  New, detailed analysis of American broadband speed tests shows a marked difference between the fastest and slowest cities and states.

The 42 million speed tests were collected across the 12 months up to 10 May this year by M-Lab, a partnership between New America's Open Technology Institute, Google Open Source Research, Princeton University's PlanetLab, other supporting partners, and compiled and extracted by analysts at

The five fastest states have download speeds around three times faster than the five slowest.

Rhode Island tops the table at 36.69Mbps while Montana sits bottom of the pile with average speeds of just 10.94Mbps.

This means that downloading an HD movie in Rhode Island would take 27 minutes and 54 seconds, but in Montana it would take 1 hour and 33 minutes.

Our interactive map, (full screen version here) shows a contrast in average speeds across America's Rust Belt, with speeds in Pennsylvania doubling those in Ohio.

Impressive download speeds are also displayed in southern states of Texas, Oklahoma and Kansas.

In a previous report complied by, the US managed to trump 168 countries but still found itself outside the world’s top 20 when it comes to broadband speeds, coming in behind 13 European countries and five countries in Asia.

Commenting on the results, Collin Anderson, independent researcher at M-Lab, says:

"This analysis provides an excellent insight into how the quality and adoption of broadband Internet services varies substantially across the United States. Urban areas, particularly on the coasts, have exceptional access compared to the midwest and rural areas, reflecting social, geographic, and economic divides.

"The M-Lab dataset is expansive, covering hundreds of millions of measurements from across the United States, contributed by a diversity of real broadband users over several years. With research and analysis such as's continued investigation, we can start to paint an important picture about how the Internet differs for people across locations and over time."
