Accepted as Evidence by a Regulator

The California Public Utilities Commission's broadband infrastructure grant rules name SpeedOf.Me as an accepted commercially available speed test. Under Decision 22-11-023 an applicant "may provide CalSPEED tests (or other commercially available speed tests, e.g., https://speedof.me) to show actual speeds or denials of service", evidence that can be used to dispute the California Broadband Map, and the same wording appears in the progress reporting rules and on the grant completion report every grantee files.

Sources: the CASF program guidelines (pages A-21 and A-34) and the grant completion report (item 6).

Consumers reach for it unprompted for the same purpose. SpeedOf.Me results appear in complaints Americans filed with the FCC about speeds below those advertised, throttling and inconsistent service, published by the Commission in its FOIA releases: one complainant pasted a SpeedOf.Me share link as their evidence, another attached their SpeedOf.Me history, and others named it among the independent tests they checked against their provider's own. These are the public's filings, not an FCC recommendation. Less than advertised speed · Throttling · Inconsistent speed

In Official Support Pages

Also named in support pages and technical guides, each one that organization's own choice:

• Elsevier's support articles for Shadow Health and HESI, its nursing-education products, list it as the connection test to use when Ookla's is unavailable. Shadow Health support →
• ABCmouse walks parents through it ("Go to speedof.me. Select Start Test."), and its parent Age of Learning tells schools to run it while students are on devices. Support article → · School Solutions →
• Tyler Technologies names it in the support pages for court e-filing. Support article →
• IDEXX lists it in the technical overview for Neo, its cloud veterinary software, among the sites a practice can use to check it has the throughput the application needs. Technical overview (PDF) →
• Switcher Studio, the live-streaming app, sets a minimum upload speed in its network requirements and adds: "We recommend checking your speed here: https://speedof.me/". Network requirements →

• National Capital FreeNet, the Ottawa community internet provider, names it on its speed page. Speed page →

Three of those are internet providers, which is worth noticing on its own: an ISP has every reason to send customers to a test that flatters it, and ours reads lower than most.

Our Data in the News

A different kind of citation: not "here is a speed test", but our measurements reported as an industry data source. The Internet Speed Atlas has been covered by the IT and telecom trade press in three countries.

• ISPreview (UK): "SpeedOfMe Ranks UK 14th Fastest in World for Broadband Speeds in H1 2026", covering the methodology, the country ranking and the per-ISP results. Read it →
• digi.no (Norway), August 2026: "Norge nummer 12 på internett-hastighet", reporting Norway's median of 85.4 Mbps against a global median of 33.9 Mbps, and naming the fastest provider in the country from our per-ISP data. Read it (archived) →
• Telepolis.pl (Poland), August 2026: Poland placed 38th of 119 countries at 48.2 Mbps, in a piece that works through why a single-stream measurement reads lower than the tests readers are used to. Read it →

The dataset behind all three is public and free to reuse under CC BY 4.0: median download, upload and latency for 119 countries and 39 US states and districts, with CSV and JSON downloads on the hub. Why our numbers read lower than on-net tests is answered in full on Real-World Speed.

In Research

Networking researchers have reverse-engineered, measured and described the SpeedOf.Me method, and cite it as one of the reference designs for browser-based speed testing. All of it is peer-reviewed except the workshop and project pages, which are marked as such.

• CAIDA (UC San Diego) lists SpeedOf.Me as one of ten platforms supported by RABBITS, its NSF-funded toolkit for reproducible assessment of broadband topology and speed, alongside Ookla, M-Lab, Cloudflare, Fast.com, Comcast and the FCC's own test. CAIDA says the project will support the FCC's Broadband Consumer Labels, the new FCC broadband maps and the BEAD programme. Project →

• Communications of the ACM 2023, Buffer-Bloated Router? How to Prevent It and Improve Performance: here SpeedOf.Me is not the subject but the instrument. The researcher saturates the test connection with a SpeedOf.Me download in order to measure the router's behaviour under load. Article → · Open-access manuscript →
• Also named as a reference implementation in ACM SIGCOMM 2022, in CAIDA's 2019 AIMS workshop report (one of "five major speed test platforms" then under study, which makes RABBITS the current chapter of seven years of CAIDA work), and in Proceedings of the IEEE 2017, which cites the SpeedOf.Me API as the JavaScript example of measuring a connection from inside a page.

One honest note. Some of this work scores every test against a saturated, multi-stream peak. SpeedOf.Me deliberately measures a single stream on the open internet, the speed a download or a video call actually gets, and it reads lower on that ruler by design. Cite these papers as documenting the method, not as validating a score, and read what Real-World Speed measures for the comparison.

In public research

• The American Library Association and the University of Maryland used SpeedOf.Me as the mobile speed-capture tool in their 2015 study of broadband quality in 2,251 public library locations across 49 states, funded by the Institute of Museum and Library Services, chosen because it ran in the browser on iPhones and iPads with no app to install. Report (PDF) →
• The Southern California Association of Governments, in a Caltrans-funded broadband strategy, lists SpeedOf.Me with Cloudflare, M-Lab and Ookla as a web-based speed-test provider. Report (PDF) →

In Textbooks and Classrooms

• Pearson, Technology in Action (Evans, Martin and Poatsy): the "Testing Your Internet Connection Speed" exercise in chapter 7 sends students to SpeedOf.Me, explains its sample-file method and reproduces its screen, credited "Courtesy of SpeedOf.Me", in every edition since the 13th (2016).
