I live in Mount Roskill, 3.1 km from the exchange as the copper flys, 1.5 km by road.

Chorus tell me that I should be getting download speeds of 10-20 Mbps but on a good day we get 5-6 Mbps and on a bad day 1-2 Mbps.
A Chorus man came today and replaced the connections at the pole and at the ETP and then tested the line and said that the absolute most that I could hope for is 7.5 Mbps.
Why the discrepancy between the Chorus Tech and the Chorus office?

When I look at the maps (from the Geekzone links) showing cabinets and exchanges there is a big black hole in the area that I live. It seems to me that the exchange is overloaded and there are too few cabinets. This seems peculiar to the Mt Roskill exchange as other exchanges have far more cabinets. When I research upgrade work in my area there is nothing slated, either cabinets or fibre. It seems that the people of Mt Roskill have been omitted for any previous cabinet plans and any future fibre plans.

Any ideas on who to contact to try to remedy this?
