As part of the roll-out and in order to ensure fair usage of available capacity Virgin Media will be rolling out a new traffic management system at peak times
Still hope 50Mbps doesn't get affected!
For customers on its premium up to 50Mb service, this temporary slowdown will only operate on upload speeds and an extremely heavy user will see this reduce from up to 5Mb to up to 1.75Mb, above its pre-upgrade level of 1.5Mb. Despite these peak time traffic management measures, Virgin Media fibre optic broadband remains without monthly usage limits.
Its being rolled out over the next 12-18 Months it seems!
File sharing
At peak times we also slow down the speed of file sharing traffic – that's services like Limewire, Gnutella, BitTorrent and Newsgroup (Usenet) traffic. You will, of course, still be able to use these services, but downloads and uploads will take longer during these peak periods.
We moderate the total volume of file sharing traffic on our network between 5pm and midnight on weekdays and midday and midnight on weekends. This policy is restricted to Peer to Peer ("P2P") applications and Newsgroups (which are commonly used to distribute large amounts of data)
Its being rolled out over the next 12-18 Months it seems!
Keep an eye on this site for when it's going live in your area!
