Internet Stability Test
A single run can hide variation, so the spread across runs is reported. Runs continue only while this tab stays open, and packet loss is not measured.

How this test works
Plan: up to 5 download plus latency runs in Full mode, 3 runs in other modes, with a 2 s pause between runs. Traffic: total download is capped at 300 MB, divided equally per run, and capped by the mode's own limit. Upload is off (cap 0). The test runs only while the tab is visible.
How to read the result
Summary for download speed and idle latency: minimum, median and maximum across completed runs. Variation: (max - min) / median of download speed, in percent; it is empty with fewer than two values. A history entry stores the medians of the completed runs. Runs that did not complete are not part of the summary.
What is typical
The test reports spread only. The sample is 3 to 5 runs.
