 Think of broadband internet as a high-performance car. Just as a mechanic needs to understand how the engine is functioning to keep the car running, researchers, policymakers, and consumers need accurate information about how the internet works to properly monitor and maintain it. Unfortunately, a lack of useful information is preventing consumers, researchers, policymakers, and other internet stewards from effectively understanding the state of broadband networks. Mechanics can't inspect a car without looking under the hood, and those who care for the internet can't make good decisions in a vacuum. Sharing information is the guiding principle behind Measurement Lab, a cutting-edge set of tools built on tenets of transparency and community. Operated by a coalition of academic and industry partners, including New America Foundation's Open Technology Initiative, Planet Lab, Google, Internet2, Skype, and more, MLAB provides rich, openly collected data on broadband performance to consumers, researchers, and policymakers. Deployed on an open-server platform, MLAB's open-source broadband measurement tools are globally accessible. Internet users can test their network's speed, latency, congestion, and more, instantly or free. Every time a test is run about 250,000 times every day, MLAB collects more data. That data adds up to the largest archive of openly collected, publicly available broadband data on the planet, over 300 terabytes of it. Internet users, scientists, anyone with the time, skill, and interest can return again and again to analyze new numbers and draw new conclusions. The more these analysts know, and the more they share, the better positioned they are to help improve the Internet. MLAB means a better Internet, which means a better broadband experience for consumers and everyone else. The MLAB platform is open for others to contribute to and build on globally.
