I'm trying to decide between ADSL or Skinny broadband.

The chorus map indicates the address has ADSL only with >10mbps speeds. Im curious to know if its really 10mbps, closer to 15mbps or nearer 20mbps. I know every situation is different but a more real world average would help me decide.

Do any of the speed tests out there keep anonymous records of previous speed tests for a street/suburb?

BTW I have line of sight with the Spark tower in our area but it is around 3km away.

ADSL speed is subject to the vagaries of interference in your local cable. That means the longer the cable, or the greater the distance between your modem and the DSLAM (Chorus' modem) then the greater the probability of interference and hence the slower speed.

The actual speed will depend on a lot of factors - see our article here: https://truenet.nz/about-broadband

That article also gives you an idea about the range of measured speeds achieved over various ADSL connections from over 700 tests per connection

Too much variation in other factors to make this worthwhile.

The best you could do is find out what speeds the people previously living in the house got - and even then it could well be wrong as they might have been running speed tests over wifi which would give an incorrect result

There is one available for the UK, and as above it's useless.

If you are in a cabinetised area you can get a rough idea from seeing how far the property is away from the VDSL >20mbps zone. It will be more like 10-15 than 15+, as 15+ ADSL would also be good for VDSL, therefore would be in the >20mbps zone (providing that exchange/cabinet is VDSL capable)

Thanks All.

The property is a new build in an existing suburb (no fibre until 2017). The >20mbps zone on the chorus map is about 75-100m away from us.

The problem is our neighbours who moved into their new build in December show up as ADSL only but their immediate neighbour shows up as VDSL available (and he is in the same zone on the Chorus map).

Perhaps the problem is the address checker as I know we are not yet on the Skinny one.

Your favourite ISP will be able to run a prequal for you which will give you a better idea of the speeds you may be able to get.

Closest cabinet is ~800m away by road (well there is one closer but its on the other side of SH2).

call an isp, ask for a prequal, that's the best indication you can get.

Even asking a neighbour could be hit and miss - what's to say their idea of fast is actually fast, testing methods, line quality. There are just so many variables!

If your preferred ISP goes into the Chorus coverage maps and plugs in the address and there is DSL service there already. Down the bottom there is Chorus reports which shows the current speed at the property.

Current speed? Isn't it just an estimate?

If it's showing current speed, I think it's misreading my sync speed. The report shows almost double the upload speed my modem does. :(

ever looked at the speeds listed wayyy out of VDSL range? definitely still lists VDSL speeds rather than ADSL estimates for a fair bit of it...
