"M-Lab, a partnership between the New America Foundation and Google meant to measure Internet connections, has given Google two years worth of actual broadband connection data, as measured by users. That's more than 300TB of data, which Google has imported into its Public Data Explorer for easy viewing and analysis. The results are remarkable.
"Measuring Internet access has been tricky for years. Sascha Meinrath of the New America Foundation told Ars back in 2009, when M-Lab got underway, that detailed network data about speeds, latency, jitter, and more used to be in the public domain until the government-run NSFnet was privatized in the earlier 1990s. Today, though, it's hard to know what speeds ISPs are actually offering (knowing what speeds they advertise, by contrast, is simple)."
