We believe that it's a conflict of interest when Internet service providers operate their own speed tests. A third party opinion is necessary and the provider shouldn't be allowed anywhere near the process. When providers host their own speed tests they eliminate the variables that you're here to test. Namely the Internet route itself. This test is unbiased, it tests and grades all providers on the same criteria. They want you to think your connection is running perfectly... but is it really?

Real Speed Test

Other speed tests, especially tests offered by your Internet provider try to eliminate routing factors. This can make your connection appear faster than it really is. If you visit many websites in the North America, Europe, Australia or Asia the results returned here will be a more realistic representation of your useable connection. Truthfully, do you want to know how fast your connection is within your providers network or do you want to know how fast it is to the locations where the websites you visit are being hosted?
