How is your Internet running?
An Internet Speed Test makes small data copies to measure your Internet performance. The window below links to the Measurement Lab, a partnership between New America's Open Technology Institute, Google Open Source Research, Princeton University's PlanetLab, and other supporting partners.
This NDT (Network Diagnostic Tool) provides a sophisticated speed and diagnostic test suitable for both the novice and the network researcher. NDT reports upload and download speeds and attempts to determine what problems limit speeds. It also provides detailed diagnostic reporting on what it finds. 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.
