Comcast Cable Speed Test / Comcast.net
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? Take the TestMy speed test and compare.
 Operating in 40 states, Comcast is the United States largest cable operator. Using DOCSIS 3.0 Comcast customers see download speeds up to 105Mbps (120Mbps w/PowerBoost) and upload speeds up to 20Mbps (25Mbps w/PowerBoost). TIME listed "Xfinity" at number 1 in their Top 10 Worst Corporate Name Changes list. Comcast High Speed Internet is now called "XFINITY Internet".

Note: Comcast has an "excessive bandwidth" policy and limits their users with a controversial 250GB per month data transfer cap. First offense will get you a warning... second offense will get your service terminated for a period of one year. In a company statement Comcast said that this rule has only effected 1:10000 of their customers so if you're using your connection normally, don't worry.
