I did query with OpenReach as to the delay. Collapsed duct that required planning apparently. Checked a few months later and still the same status, but only this time they blamed it on the council. Checked with the council and they haven't received any application for said roadworks. FTTC rollout in Huddersfield has been dead since the first cabinets went live.
The BT DSL checker has actually removed the date for the majority of outstanding cabinets.
Plenty of us in the same boat with these delays. A couple of delays you can probably accept. Continious delays IMO point to bad management, no matter how complex the project.
