Totally unrelated note but we're actually moving into our new house in Whickham on Friday. We're on cab P16 though. Anything we should know before we move?
Codelook currently has that cabinet at: FTTC being Connected, live due by May 2016
I can't see much in the way of roadworks in the area, there's a lot going on with Virgin Media. Whereabouts is P9? Is it the bit down by Swalwell? I remember having a look at a house down there, but was put off by the lack of both FTTC and VM. In the end we found a better house for us further up the bank, which has both FTTC and VM.
I can only assume BT are either having all sorts of problems with collapsed ducts, or the cost of connecting the cabinet to mains power is proving either very expensive or is a difficult project that may take a bit of time.
Keep an eye on roadworks.org (enable the roadworks filter and set the time range up to 12 months) and see if anything pops up there. Normally the description will let you know what work is planned.
