Your data stays with you. All tests run locally in your browser — results are not uploaded or collected anywhere.
The only outbound traffic from this page is the probes themselves — requests to the Microsoft and public endpoints being measured (e.g. Microsoft 365, DNS-over-HTTPS, GeoIP lookups) so the diagnostic can assess real connectivity. Test results stay in your browser. Exports (Text / JSON / CSV / Email to IT / Copy Share Link) are produced on-device and only leave your machine if you share them.
How it works: Click Run Browser Tests to execute tests that can run in your browser (endpoint reachability, latency, location, WebRTC). For deeper diagnostics (raw TCP/UDP, WiFi, system proxy, registry), download and run the Local Scanner — it will automatically open this page with results.
