Based on the maps at gis.geek, it seems like there's a pretty significant quantity of copper services that are essentially POTS only. With Spark withdrawing POTS services, would these runs be effective, despite the fact Chorus is unable to remove the copper from many of these runs (as many of them are rural without fibre access), would this potentially lead to a situation where Chorus is still forced to maintain the copper despite there being no services accessible through it? Spark's website is rather vague on whether there will be any copper services going forward outside of fibre areas.
