Global NDT test nodes
Browse production M-Lab machines configured to provide NDT measurements, regardless of their distance from you.
Infrastructure directory, not a live availability promise
This page is built from M-Lab's official Siteinfo inventory. It includes active production machines in the mlab-oti project that are configured with the NDT service. It excludes staging and sandbox machines.
A listed machine may be offline, under maintenance, or temporarily unable to accept a test. Actual speed tests still use M-Lab Locate, which supplies a short-lived access token and selects currently eligible servers. Distance is not used to hide entries on this directory page.

The machine names shown here identify M-Lab infrastructure. They are not direct, reusable NDT7 connection URLs. M-Lab requires test clients to obtain complete URLs and access tokens from Locate.
