We are currently moving office, and in the new location we have been offered BT's Wholesale Ethernet as an alternative to a traditional leased line. It seems to be full-duplex, symmetric, uncontended, with a similar SLA to a leased line, but comes in at less than half the cost. 2Mbps is approx £300/month and 10Mbps approx £630/month.
Does anyone have any real-life experience of this product? I understand that it's fairly new and part of BT's 21CN network upgrade. Unfortunately fibre is not available in the building.
