Whilst not absolutely impossible, it is extremely improbable that the houses either side of you are fed from a different cabinet.It is far more likely to be a records error.
Thanks @licquorice
I've gone and contacted Openreach to see what is going on.
They came back an hour or so ago saying that they will investigate and will need the help of their lineloss team.
Which exchange are you on, you have deleted it from the screenshot? I assumed Mildenhall from the message in yellow, but it would appear that that message appears regardless of location.
Its Huntingdon @licquorice
Hello neighbour, I'm about 10 miles away. 😁
That's totally weird, cabinet 17 is nowhere near cabinet 80
Are you in Brampton or Hinchingbrooke?
😯neighbour! didn't expect to find people around me here!
We will be in Hinchingbrooke close to the park.
Hopefully Openreach will have a good news for me next week.
In that case, I very much suspect it is a database error and you will be connected to cab80 with good speeds.
