A company has done real download speed tests in multiple US cities and Idaho has come last at 318 kbps. This is in the same range as much of South Asia. The slowest city, by the way, was also in Idaho: In Pocatello, it would take nearly 12 seconds to download that music file, according to the study by Pando Networks, a company that helps consumers accelerate downloads. In the nation’s fastest city, Andover, Mass., a Boston suburb, it would take just over one second.
