The data for this report comes from Visual Networks. Through its Internet BenchMark data, Visual rates national, regional and business-to-business Internet Service Providers according to several factors, including call failure rate, modem conect speed, and Web download performance.
We took the raw data from Visual and applied statistical analysis to rate the relative performance of each ISP. We then averaged out the data for each category and list those ISPs that perform above the average for that group. If your ISP is not listed (check the list to see all the ISPs tested) for that category, it means they performed average or below for that category.
A list of all the ISPs tested, as well as an archive of previous reports, appears below.
