Some places get everything...
... most seem to get nothing.
The nearest places to me getting full fibre seem to be the ones that already have Virgin, got 4G early and are getting 5G this year.
Perhaps it's the infrastructure or population density, but the sceptic in me suggests that Openreach are going for market share.
Meanwhile, many places will be stuck on ADSL / VDSL and poorer mobile coverage for a lot longer.
