The U.S. Federal Communications Commission on Thursday launched a broadband test service to help consumers clock the speed of their Internet.

Located at the site www.broadband.gov, the test is aimed at allowing consumers to compare their actual speeds with the speeds advertised by their providers. The FCC release follows an FCC meeting in September where officials said that actual speeds were estimated to lag by as much as 50 percent during busy hours. “The FCC’s new digital tools will arm users with real-time information about their broadband connection and the agency with useful data about service across the country,” FCC Chairman Julius Genachowski said in a statement.

The FCC is also collecting information about where broadband is not available. Consumers can email the FCC at fccinfo@fcc.gov or call the FCC.
