Perform a Fiber speed test

You have probably used speed test sites to test your Internet connection, but many speed test sites are not designed for ultra-fast services like Google Fiber Gigabit Internet. To enable you to accurately measure your connection speed, we built a speed test that can handle Fiber.

To test your connection speed:

  1. Open your browser and go to the Fiber speed test site.

  2. Click Start the speed test.

The speed test checks your upload and download speeds and displays the results.

You can also check your speed with

To test your connection speed:

  1. Go to

  2. Move the mouse pointer over the triangle in the middle of the screen.

  3. To the right of the triangle, click the box labeled Hosted by Google Fiber.

The speed test checks your upload and download speeds and displays the results.

For best speed test results, follow these tips:

  • Make sure you use the latest version of your web browser to run the speed test. Read about supported browsers.
  • Quit all applications on your computer before running the test.
  • If you have Fiber TV service: remember that both TV and data come into your home through your Fiber Jack, and TV takes priority. To maximize results, run your speed test when you're not recording any programs, and turn your TV Box off. 
  • If possible, run the test on a recent model computer with up-to-date networking hardware.

If you have pop-ups blocked, the speed test might not appear when you click the speed test link. In that case, you can temporarily unblock pop-ups to display the speed text page.

If the speed test links don't work for you, try this alternate link.
