There is an outside chance that Sky has congestion issues and is waiting on a move from a 1 Gbps handover link to 10 Gbps handover link, but impossible to know from the vague language used.

That isn't Openreach's problem so shouldn't trigger an order being kicked back by them. Entirely down to Sky I believe.
