Formally the M-Lab speed test, although often referenced to as the Measurement Lab speed test, became available in January 2009.
M-Lab is a mainstream speed test. In other words, the results are in line with the advertised speed.
M-Lab was the number 2 speed test in the ultimate speed test test 2022 (number 1 was Google Fiber).
M-Lab considers their speed test as a Network Diagnostic Tool (NDT). The way M-Lab's NDT works has evolved over time.
M-Lab was founded by New America’s Open Technology Institute, the PlanetLab Consortium, Google, and a group of academic researchers.
Nowadays M-Lab is a fiscally sponsored open source project of Code for Science and Society .
As stated at the about page: (...) M-Lab is an open source project with contributors from civil society organizations, educational institutions, and private sector companies (...) M-Lab aims to advance Internet research by empowering consumers with useful information about their Internet performance (...)
Google is a founding member of M-Lab and still supports it, hence it isn't that strange the when you Google speed test, you get the option to start the M-Lab speed test directly.
It is striking that the two best speed tests according to the ultimate speed test test (Google Fiber and M-Lab) are related to Google. Well done Google.
