Accepted as Evidence by a Regulator
The California Public Utilities Commission explicitly names SpeedOf.Me as an accepted speed test in its broadband infrastructure grant rules. Decision 22-11-023 allows its results as evidence for challenging broadband-map coverage, reporting progress and completing grants.
Sources: the CASF program guidelines (pages A-21 and A-34) and the grant completion report (item 6).
Consumers have also submitted SpeedOf.Me results and test histories in FCC complaints about slow, throttled or inconsistent internet service. The Commission published these in its FOIA releases. These are consumer filings, not an FCC recommendation. Less than advertised speed · Throttling · Inconsistent speed

Milestones
Boilerplate
SpeedOf.Me is a browser-based internet speed test that has measured real-world connection performance since December 2011.
Launched in December 2011, SpeedOf.Me measures real-world download speed, upload speed, latency and jitter in the browser, with nothing to install. It runs a single stream against neutral servers on the open internet to reflect everyday browsing and downloading. The same engine is available to developers as the SpeedOf.Me API, and its anonymized results power the Internet Speed Atlas.
