These are the states with the fastest — and slowest — internet speeds

The District of Columbia retains the top spot for fastest wireline internet in the country at 28.1 megabits per second, according to content delivery network Akamai’s latest State of the Internet Report. The fastest state is Delaware with an average speed of 25.2 Mbps. D.C. and Delaware are the only two places in the nation that currently surpass the FCC’s 25 Mbps broadband threshold.

At 18.7 Mbps, nationwide average internet speeds are up 22 percent year over year. The U.S. ranks 10th in wireline internet speeds and 28th in mobile internet speeds.

All the states posted substantial year-over-year gains in internet speed as U.S telecoms roll out faster networks. Ohio’s average speed increased the most at 74 percent while Utah saw the least growth at 4.9 percent.

New Mexico and Idaho round off the bottom of the list, with average internet connection speed of 12.4 Mbps and 12.0 Mbps, respectively. That’s less than half the speed of the fastest state on the list, Delaware.

Here’s the complete list of U.S. average internet speeds:
