NDT is a diagnostic test that measures using a single TCP stream. The single stream “speed” metric doesn’t measure link capacity, but rather how well a single TCP stream can take advantage of that capacity.
This report displays aggregate M-Lab NDT data from M-Lab's statistics pipeline service. Review the documentation on available statistics and methods, or contact support@measurementlab.net for support before using this data in your own reports.

Estimated Median
NDT statistics used in this report are provided as daily histograms, consisting of the percentage of measurements within a range of "service levels" or speed ranges.
The chart on the top left presents the histogram of tests that measured at these levels over the selected date range and locations, across all providers.
The daily histograms also allow us to provide the log average or geometric mean over the selected days, and median daily metrics, Finally, we provide the estimated median metrics over the dates selected, by displaying the median of each day's median.
