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?
