How To: Test If Your ISP Is Throttling Your Internet

After hearing all this hubbub about Comcast's violation towards net neutrality with BitTorrent throttling, we had to take a closer look into the matter. Using Google's new tools, located at Measurement Lab, we were able to determine if our ISP was a little bit too much like Big Brother when it came to how we were using out Internets. Now, it's your turn.

"Google's broadband test tools are located at On that page, you'll see an first icon that says "Users: Test Your Internet Connection". Click that, and then you'll be taken to a page where there are three tests available, and two more listed as coming soon. However, out of the three available tests, only one of them is fully automated and easy to use."

That test would be Glasnots, a simplified solution of novices to test if their ports for BitTorrent are blocked or throttled by their ISP. Turn off all your downloads, make sure you got Java, and then run the Full Test. If the servers aren't overloaded, the test should take about 5-7 minutes to complete, depending on your connection.

So, we found that Comcast in our area hasn't been fiddling with our Internet connection. How did your ISP fare?
