Virgin Media has announced that it is to start throttling the bandwidth available to users of peer-to-peer (P2P) file-sharing over its network.
Unlike the majority of DSL-based broadband providers, the cable operator has so far placed no restrictions on the use of file-sharing, only penalising specific users who hog more than their share of bandwidth under its 'fair use' policy - something it will continue to do in addition to the new regime.
Under the new rules, Virgin will cut the amount of bandwidth allocated to peer-to-peer protocols and Usenet traffic. The restrictions will be phased in between now and next summer.
The limits placed on file-sharing and Usenet traffic will vary, depending on the overall load on Virgin's network - but the company will reserve at least 75 per cent of available bandwidth at all times for ordinary browsing, as well as time-sensitive data such as streaming video.
To soften the blow, Virgin is boosting upload speeds for all users. Customers on the M and L packages will see their upload speed double from 512Kbit/s to 1Mbit/s. For XL, the thereotical maximum will become 2Mbit. Customers on Virgin's most expensive tariff, XXL, will see their upload speed rise from 1.5Mbit/s to 5 Mbit/s.
The downside for customers with XXL accounts is that, for the first time, they'll see their connection speed clobbered if they upload too much data.
