A shiny new Huawei cabinet has popped up a few metres from the cabinet I'm connected to. We're in the upgrade area covered by Kent County Council / BDUK, and according to the program the upgrading is supposed to start between April and September 2014. So it looks as though they've started slightly early, although I realise it can be many months before the service will be available.
I've paced out the distance from my home, and it's 240 paces (~200 metres), and there's little doubt that the wires travel straight along the road, so I have hopes of a respectable speed.
