I emailed openreach about P10, and got this:
"Thank you for enquiring about fibre broadband.
When installing fibre broadband we can't necessarily install all the FTTC cabinets for delivery in the same phase. This is the case for your cab, NE/MP 10, which, along with others on Morpeth exchange, will be delivered later this year.
At this point, as we are still in the build phase and I cannot give you a date when your cab is expected to go live.
Keep monitoring our web-site which will give details."
At least this confirms that I'm actually /on/ P10, and that they are getting on with it. The lack of timescales is as infuriating as ever.
