We have a weird internet set-up at home, with our connection coming in from a device on our roof instead of via fibre or ADSL. It mostly works okay, but if the provider starts to oversubscribe connections then our speed suffers, especially at peak times. We had some extended periods of poor service when the service first went live but we stuck with it and over the past year or two it has worked mostly okay. It’s not stellar, but it’s cheap and unlimited.

In January we started no notice that we were struggling to stream at peak times and my wife was having issues browsing on her phone. I figured that this might be a good time to switch to fibre, it’s around £15 a month more expensive, but bound to give us a more stable connection and it would be faster too.

I logged into my router to find out how much data we use so that I could price up the right fibre package, and noticed something strange:

During a standard month we usually download around 500gb of data, and upload 50-60gb. In January we downloaded 450gb, but wait, what the.. we uploaded 807gb. We’ve already uploaded nearly 700gb this month too, in total nearly 1.5 terabytes of data and more than we’d use in two years. Something was very wrong somewhere.

My instant reaction was to ask my teenage daughter if she had anything on her laptop that might be uploading stuff. Torrents? She offered me a blank look. Then I remembered the torrent client running on our home server. And there was the problem: three torrents had been seeding endlessly since the end of December, to the tune of 1.32 terabytes. Whoops. Theoretically uploading shouldn’t affect download speeds, but I think that my creaky network was saturated by the constant transfers. Lesson learned.

Anyway, to those lucky people that were able to download a particular torrent 987 times.. you’re welcome.
