Check If Your ISP Throttling Your BitTorrent Downloads

Ads by Google

bittorrent-throttling-test So the cat’s been out of the bag for a while now that ISP’s are throttling or in some cases even blocking your BitTorrent downloads or seeding.

Comcast came out and admitted to it’s practices in the United States last year. You can read about it here on wired. Since then there has been lot’s of speculation on if other ISP’s are doing the same thing”¦

What do you think?

Yeah we do also!

Now there is a free tool that will simulate BitTorrent activities and let you know if your speed or activities have been effected and to what extent. This program (aka bittorrent throttling test) and group have picked up momentum since 2008 and now have the backing of Google and other big names.

Are you curious as to if your ISP is throttling your torrent downloads and doing you dirty?

Well so are we.

Run the tool below on any web browser on any operating system and post back what your results are in the comments. It is strictly web based and nothing gets installed. So you can try it pretty much anywhere.

I tried this in the office on my Cogent circuit. It is a 100mb Ethernet handoff so I was not really expecting any throttling. All you need to run the test is browse on over to:

You will be greeted by a web page that looks like this:

torrent throttling isp

Simply scroll down on the page until you see the Start Testing button. You can run the detailed or the simple test. The only difference is the intensity of the test. Some ISP’s are believed to only throttle torrents after a certain period of time (greater than 5 minutes) so this will have you covered.

After you hit the Start testing button your test will begin and you will see a count down in a window that looks something like what you see below.

When the test is complete you will get your results. They will also look something like mine which you can see below. My ISP is NOT throttling my BT downloads or seeding activity and they go into detail on each point they checked as well as the speeds they were able to achieve with the transfers.

I love geeky statistics. Here are my results:

check if your isp is blocking

I had a buddy of mine run this against his machine on Comcast in Manhattan and his results came through with Throttling and max speeds of only 25kbps”¦ Whoa that’s slow! Thanks for the tip El Di Pablo!

Post your results in the comments. And if you have another method of testing if your ISP is getting it’s grubby hands on your torrents post that as well. Don’t be shy kids :)

    i feel these results are inaccurate, as my seeds are still choked around 3bps on average (if anything decides to seed at all)

    Is BitTorrent traffic on a well-known BitTorrent port (6881) throttled?

    Ok so I use Verizon Fios in Fort Wayne and my upload is supposed to be 5mb and my download is 20mb. Regular broadban test show that these numbers are right on. But when I went to the test it told me that there was no problem but the download streams where only at 3mb which when downloading off of utorrent my speed always maxes out at 2.4mb. So are they throttling me?

  • olddog_newtricks

    sorry, how does this work?
    the instruction “browse on over to:

    a title=”http://broadband.mpi-sws.org/transparency/bttest.php” href=”http://broadband.mpi-sws.org/transparency/bttest.php”>http://broadband.mpi-sws.org/transparency/bttest.php.

    doesn’t mean much to me.
    are all the quotation marks, and the final full stop and the initial text of ‘a title=’ (enclosed here in single quotes by me for clarity, i hope) required?

    thank you -someone- for assistance.

    The link isn’t coded in the article so it appears in firefox.

    This is great! I’m checking my connection right now.
