The Network Diagnostic Tool (NDT) provides a sophisticated speed and diagnostic test. An NDT test reports more than just the upload and download speeds — it also attempts to determine what, if any, problems limited these speeds, differentiating between computer configuration and network infrastructure problems. While the diagnostic messages are most useful for expert users, they can also help novice users by allowing them to provide detailed trouble reports to their network administrator.

This NDT test uses WebSockets. Most modern browsers should support running this test. If you are experiencing problems, make sure that your browser has javascript enabled and supports WebSockets.
