Do you think that BT deliberately delays a go live date just to annot people. Just because te cabinet is live does not mean it is fully connected, tested, all data bases updated and aligned, routing information built and stored &c &c.
The sooner BT can sell capacity in the cabinet, the sooner they get some money back. The sooner they have some more money, the sooner they can pay for another cabinet install ... the sooner the next is installed and ready the sooner BT gets revenue from it, and so on until the country is fully covered.
