This started when my internet connection suddenly slowed to a crawl, which turned out to be OneDrive uploading 4K video files.  While looking for the problem I was 'trying' to use Ookla, and when things started working again, I found myself looking at my neighbour's connection speeds, and got a surprise.

I am rural (8 kilometres from Blenheim) but we have a cabinet 350M up the road.  However my road is a cul-de-sac and the cable obviously goes down the other side of the road, and back up my side, making my effective distance from the cabinet 850M.  There is a school opposite the cabinet for what that's worth.

My question is why are the speeds not linear with distance? (According to the wee map/chart below) There are bumps in the curve like where #6 (Ashford Grove, Rapaura) appears to have better speeds than #4 despite being further away?  My own download speed (#1) is better than #5 and #7 despite them being effectively closer to the cabinet?

I don't remember seeing the 'Available on request' option for fibre the last time I checked Chorus, and while I am happy with my VDSL speeds, there are times, like tonight, when the slower upload speed causes problems.  They ran fibre to the cabinet in 2012, but it is on the other side of the road to me so would a custom installation be crazy expensive?  Is Jacinda sitting on her laurels regards VDSL, or might we one day get free fibre connection living outside of town?
