(Ookla is owned by the same parent company as CNET and Ziff Davis.)

What does that mean? Can you tell us that AT&T offers the fastest internet plans available to customers across the country? no.

Why do you care about speed tests?

CNET’s ISP review highlights that speed test data can be a useful diagnostic tool. This is a snapshot of your internet connection performance at any time. For example, it helps to identify When and where connections may be delayed. But that’s not an exact science. Many things can affect speed tests, such as whether you are using them Wi-Fi or Hard Wired Ethernet Connectionwhen the test is running, etc.

To be included in Ookla’s SpeedTest connection report, your ISP must display at least 3% of the data collected in the 6-month window. That means some Fiber Optic Internet Provider National performance may work particularly well, but if they are more regional and can’t hit the lowest share of the national market, they won’t show up to the top. Google Fiber That’s a good example. This was the fastest provider in nine of the country’s top 100 cities (only the second in AT&T Fiber), but it did not reach enough households to meet the Ookla mark for national inclusion.

Yes, grabbing the top spot is certainly something a company like AT&T can boast about. After three consecutive wins last year, CEO John Stankey said in a press release: “Ookla’s results confirm what we already knew in the market. Fiber experience wins in one mile.

There may also be smaller or more local providers that may make more sense to you. Speed test results can be a key factor when choosing a broadband provider, but they should not be the only consideration.
