On May 25, 1961, President John F. Kennedy announced there would be a man on the moon by the end of the decade. That goal was achieved on July 20, 1969. The complexity of that task must have been huge and yet one giant leap happened on time; in fact six months earlier than thought.
By comparison getting FTTC/FFTP to customers by a suggested date must be a walk in the park. So the OP does have a point without being lectured about not understanding the trials and tribulations of large engineering projects.
True, I have been told to keep checking the Where and When Page by BTOR via email and BT over the phone and email and the following:
Itís where we publish the very latest fibre coverage information and we update it weekly.

So if its updated on a weekly basis then they could add some extra info instead of the default option in the list.
But having the current BTOR Where and when page is better than having nothing, even though it breaks a lot
