I ordered on 30th December on KCI2 Assure (UG fed).
Openreach turned up on 31st to check the duct and found it blocked a dig was advised within 7-10 days, Roadworks site was showing as work due yesterday and today which was slightly longer due to New Year. Whilst there is no evidence of a dig, a blue rope has appeared today, so looks like someone has managed to rod the duct with a bit more oomph and cleared whatever the blockage was.
The original live date was for the 17th but that is now showing as 17th Feb for Fibre and 17th Jan for copper. Now crossing fingers they can pull it forward again.
