It was only a matter of time before they did it, got this today by email:
We’re making some changes to help your O2 Home Broadband flow better in October ’09.
The internet is busiest between around 8pm and 11pm, when most people are at home and online. This can slow it down for everyone.
To stop that happening, we’ve introduced a traffic management policy for our Access package on O2 Home Broadband.
From now on, we’ll give first priority to those things most people want to do in the evening – like emailing, looking at websites, watching things on sites like BBC iPlayer or YouTube, or using programs like Skype or Messenger.
We’ll give lower priority to peer to peer programs and newsgroup services, find out the details. So you’ll notice them running slower when our network gets busier. We’ve done this because some people use these programs to download large files (like movies and TV shows) all day long. And that slows everything else down.
How traffic management works
We’ll only do it at the busiest times (from 8pm to 11pm or whenever our network is congested).
You can still use any kind of program, whenever you want. But peer to peer programs and newsgroup services will run slower when our network is busy.
Audio and video streaming (like BBC iPlayer and YouTube) will work as normal – or even faster.
We won’t limit your actual connection speed – only the speed of peer to peer programs and newsgroup services.
