Our data comes from eTesting Labs and its Internet BenchMark division. Network World takes the data and applies statistical analysis to rate the relative performance of each ISPs compared to the other ISPs within the same market classification (national, regional or business-to-business ISP). Based on that analysis, we rank the top ISPs for the month listed. The chart at right lists the top three ISPs that perform above the average for the metric listed within that classification.
A list of all the ISPs tested, as well as an archive of previous reports, appears below.
