There are websites for testing the own internet speed offered by a lot of providers. The most services of this kind collect multiple local data in such tests, which is why they are not without risk from a data protection perspective. The open source alternative LibreSpeed offers a data-efficient alternative.

Data collection of conventional speedtest-alternatives

Traditional providers of internet speed testing services collect a large amount of data from their own networks, own devices and from the applications on it. In connection with the aquisition of Ookla (operator of Speedtest and Downdetector), the international consulting firm, Accenture, announced that more than 1,000 attributes are queried per test in March 2026.[1]

  • When it acquired Ookla, Accenture announced that more than 1,000 attributes are collected from the user by Speedtest or Downdetecor.

  • Download speed
  • Upload speed
  • Ping

LibreSpeed.org had not enabled this feature as of April 29, 2026, however.

Ookla’s platform, which captures more than 1,000 attributes per test, provides the foundation for these insights.
