If your Internet has been slowing down lately, Google can help you. The company has helped create a tool to tell whether a problem is caused by your broadband ISP, the application, your PC, or something else. It's about time. We all deserve information about the services we pay for and this should make getting the Internet info much easier.
Measurement Lab is particularly useful if you want to find out if your ISP is purposely (or accidentally) slowing down peer-to-peer network traffic for your machine. It's a relatively new issue. ISPs slowing some kinds of traffic, but it's likely to become more widespread. I predict in the next couple days computer geeks will find out some very interesting things about how big ISPs handle your Internet.
Run, don't walk right over here to check out your connection yourself. It's free, like most Google-things.
