I thought I would correct you there by saying its been upgraded to FTTC and not FTTP.
Exchange name: Whitehead
Exchange status: Fibre enabled
Cabinet number: 14
Number 100 on that postcode can only get the following shows that they cabinet isn't close by:
[VDSL Range A Clean]
Downstream: 18 to 26.2 Mbps
Upstream: 3.7 to 5.9 Mbps
[VDSL Range B Impacted]
Downstream: 9 to 20.6 Mbps
Upstream: 1.3 to 5 Mbps
So cabinet 14 is just too far for some homes.
Its also down to how the cables are routed, some of the cables might just be too long.
But yeah, I can also see that some of the odd number addresses are listed as being too long.
So this is showing the copper line is going up the road one side and then back down the other.
Also some of your postcode are on cabinet 30 and 41.
