Perform a Fiber speed test
Although you might have tested your Internet connection speed using one of the available services such as speakeasy.net, many sites are unable to accurately measure ultra-fast connections like Fiber 1000. To provide accurate speed results for your Fiber service, we've built a speed test to accurately measure Fiber's speed.
Both video and data come into your home through your Fiber Jack, and video takes priority. If you have one or more TV Boxes turned on (even if your TV is off and you are not watching), the video stream to the TV Box is using part of the gigabit bandwidth, and the data stream can use only the remaining bandwidth. If you don't have Google Fiber TV service or have all of your TV Boxes powered off, the entire fiber pipe, or channel is available for data.
In addition, speed test results can be severely impacted by slower/older computers.
To test your speed:
For the best results, close all applications before running the speed test.
Open your browser and go to speed.googlefiber.net.
Click the play button to start the test.
The Google Fiber speed test checks your upload and download speeds and displays the results.
