Measurement Lab detects blocked or throttled ports

Google, the PlanetLab consortium and the Open Technology Institute today launched the Measurement Lab (M-Lab), an open platform for Internet measurement tools, along with three tools for users to test their Internet connections - including Glasnost, which tests whether BitTorrent is being blocked or throttled.

The M-Lab launch is aptly timed, with Cox Communications, the third-largest cable provider in the US, set to start a new "conjestion management" scheme that will give less priority to "less time sensitive" traffic such as peer-to-peer traffic and file uploads - a scary thought for Gizmag, with so many of our employees completely reliant on moving large files around the web on a daily basis.
