After looking around it looks like the speeds in your area from the FTTC cab have dropped with the amount of crosstalk. This has led to your area being removed from the OR checker for FTTC, likely ADSL speeds are actually better !
Cabinet P38 is somewhere in postcode M7 1PA, according to Codelook. Trying addresses in this postcode (Meadow Road) I get only "Your address has been successfully matched; however we cannot determine ADSL availability at this address."
So I tried a property in a directly adjacent postcode (M7 1RF, 1 Clover Drive) and got a result with no FTTC availability shown.
Whilst it's possible the copper takes an extremely circuitous route, to get down to even 25M it would have to be over 1km.
Looking from outside, it seems database breakage is more likely explanation than crosstalk.
