Virgin Media customers living in Preston, Wigan, Blackpool, Camden, Dalston, Enfield and Haringey will shortly become test subjects for an adjustment to the operator’s broadband (cable) traffic management policy.

Under the Existing Policy customers would only be affected if they downloaded an "unusually large amount" during peak times (4pm till 9pm). However, an official statement posted to Thinkbroadband's forum (here) suggests that the new policy would add two additional time periods:


The time periods are not cumulative, meaning that if you download too much in one period then it wouldn’t be carried over into the next. Those found to be downloading too much on the M and L packages will find their speeds dropped to 1Mbps downstream and 128Kbps upstream, while XL customers would be reduced to 5Mbps downstream and 192Kbps upstream.
