I'm about 200m from Auckland Central exchange so am keen to know.
is that the line of sight distance between your front door and the exchange, or in wire distance between your wall jack and their dslam?
i've seen instances where people are a couple of km from an exchange but have more double that distance in wires. Also two neighbours - one connected to the new shiny cabinet in between their houses, the other at the end of a very long, unstable wire to the nearest exchange..
you've probably got a decent line, but you just never know... :)
