RYE BROOK, N.Y. — Ohio is now among states with the slowest, average internet speeds in the U.S. – though Buckeye State residents may not have noticed a change in their service.

According to New York-based technology firm Broadview Networks, Ohio in the past three years dropped significantly in the ranking for fastest, U.S. internet speeds. In 2014, Ohio was ranked 19th, with 11.0 megabites per-second (Mbps). According to data gathered earlier this year, Ohio dropped to no. 47.

While Ohio’s speeds have not decreased over the past three years, Broadview’s data shows that Ohio is the only state whose internet speed has not improved. Even Idaho, who was ranked the slowest of all 50 states, has improved slightly since 2014, increasing from 7.7 to 10.6 Mbps.

Washington D.C. reportedly boasts the fastest internet speeds in the nation, with a speed of 22.5 Mbps. That leaves an 11.9 Mbps difference between the fastest and slowest states.

Broadview Networks created the graph by using data collected by Akamai, a content delivery network that specializes in ensuring the reliability and security of the internet. Akamai uses the data to report on issues such as online connectivity, cybersecurity trends and metrics, internet connection speeds and more.
