Also when VM run a speed double programme the device does sync up at double the speed - though whether this then causes undue congestion on the network is of course a different point!

When BT announce a speed double programme they may roll it out nationally in one go but given the technology they use it doesn't change things for a lot of users.

While I don't have Infinity I checked the reported likely speed before - 34 Mb/s and after the speed double programme it still reports a likely speed of 34 Mb/s - so how would BT's speed double programme help me? As I understand it it will only help if you were running at 40 Mb/s before.

One of BT's challenges is in many cases an old rotting copper cable network.

As Ben say Virgin is still running with equipment in some cases 10 years old and also inadequate capacity at the local end to provide a consistently well performing solution in many locations.

Surely Virgin should start investing in replacement equipment for this ancient technology they still support, but also at the same time implement proactive capacity management. They are gathering statistics on utilisation so they should be in a position to plan capacity relief before it has an undue impact on customers.
