So as of today, I'm back to 'Zero'.
I caught an OR chap poking around today and it turns out he was there to "sign-off" before go-live, except that our house and 3 others have been classed as having wayleave issues and so we won't be going live. The other 3 houses closest to the DP with CBT have now gone live on dslchecker, but not us
The engineer didn't know what the wayleave issues where, but I did help him identify and literally dig out the chamber that had the ducting already in place for our copper that goes from the CBT pole to our houses, so there is definitely a route already in place.
Is there anything I can do here other than start hanging ethernet between our houses!?
