BT slams bandwidth brakes on all subscribers
BT is throttling all of its broadband customers' bandwidth at peak times, not just heavy users, according to independent monitoring data.
Early findings from a new hardware-based monitoring project by ISP analysis outfit Samknows show that even customers who use their connection lightly have non-port 80 traffic slowed to about 15 per cent of the normal speed in the evening, when load on BT's network is high.
Port 80 is used for HTTP web traffic. Samknows used tests on other ports to simulate peer-to-peer traffic, so even a casual BT downloader who grabs a TV show from BitTorrent faces the throttle.
