Akamai's numbers, released Monday in the quarterly State of the Internet report, is based on 533 million unique IP addresses from 233 countries and regions that accessed the Akamai network in the third quarter of 2010. Although two-thirds of U.S. connections are below 5 Mbps, there are enough fast connections to bring the United States' average speed up to the 5 Mbps mark. South Korea leads the way in this category as well, with the average user enjoying speeds of 14 Mbps.
While the FCC defines broadband as download speeds meeting or exceeding 4 Mbps, Akamai defines broadband as 2 Mbps and greater and high broadband as 5 Mbps and greater.
Within the United States, Delaware leads the way at 64% of Internet connections hitting the high broadband mark, with New Hampshire and Rhode Island also surpassing 50%. The District of Columbia and Massachusetts round out the top five at 47% and 45%, respectively, according to Akamai.
"Ideally, these positive trends in high broadband adoption will continue to increase over time, especially as additional funding for broadband programs is awarded by the United States government," Akamai said. "In July, $795 million in 'broadband expansion grants' was awarded to projects in 36 states and the District of Columbia. Additionally, $1.2 billion in funding was awarded by the Rural Utilities Service in August, mostly for rural DSL and wireless expansion."
The Akamai report also details Internet attack traffic patterns, which show the United States accounting for an increasing share of Internet attacks, with 12% of all attack traffic originating from this country.
"The United States remained in first place during this period, responsible for nearly one-eighth of the observed attack traffic -- slightly more than in the prior quarter," Akamai writes.
Previously, the United States accounted for 11% of worldwide attack traffic. Russia, meanwhile, dropped from 10% to 8.9% and China dropped from 11% to 8.2%.
