The FCC is collecting and storing street addresses, IP addresses, and broadband performance information through these speed tests. (The FCC is not collecting email addresses through these speed tests.) The street addresses will not be released, disclosed to the public, or shared with any outside entities, including M-Lab, except in the limited circumstances described in the Consumer Broadband Test Privacy Statement. The FCC, and M-Lab are collecting and storing broadband performance information and IP addresses, which M-Lab may release to the public. The FCC will not make individual IP addresses available to the public except in the limited circumstances described in the Consumer Broadband Test Privacy Statement. For more information, see the complete Consumer Broadband Test Privacy Statement, the M-Lab Privacy Policy. The FCC is soliciting this information under authority of the Broadband Data Improvement Act of 2008, Pub. L. No. 110-385, Stat 4096 § 103(c)(1); American Reinvestment and Recovery Act of 2009 (ARRA), Pub. L. No. 111-5, 123 Stat 115 (2009); and Section 154(i) of the Communications Act of 1934, as amended.


By taking this test, you will help the FCC learn about the state of broadband in the U.S. Data from this test is sent to the FCC and will be combined with other results to help build a map of broadband availability. The test currently runs exclusively on the Measurement Lab (M-Lab) platform. If you are interested in using an alternate test, another free popular consumer broadband testing tool is available from Ookla at www.speedtest.net. For more about the differences between the two testing methodologies see the About section.

Note: the M-Lab application currently does not work with Safari, Chrome, and Opera web browsers.

This application will transfer a small temporary file back and forth to test the quality of your broadband connection:

  • Download Speed: The speed at which data is sent from the testing server to your computer.
  • Upload Speed: The speed at which data is sent from your computer to the testing server.
  • Latency: The time it takes for data to be sent from your computer to the testing server and back (the "round trip time").
  • Jitter: The variability in the delay between your computer and the testing server.

The test will run on the M-Lab platform. The FCC requires the street address from where you are connecting to the internet because it may use this data to analyze broadband quality and availability on geographic basis. For more information see our About the FCC Consumer Broadband Test page.
