Google unveiled its Measurement Lab (M-Lab), an open platform that researchers can use to deploy Internet measurement tools. 
Over the course of early 2009, Google will provide researchers with 36 servers in 12 locations in the U.S. and Europe. All data collected via M-Lab will be made publicly available for other researchers to build on.
Google said its M-Lab is intended to be a truly community-based effort. The idea for M-Lab was developed with the New America Foundation’s Open Technology Institute, the PlanetLab Consortium, and academic researchers.
three tools running on servers near Google’s headquarters are available to help users attempt to diagnose common problems that might impair their broadband speed, as well as determine whether BitTorrent is being blocked or throttled by their ISPs.
