In an area with such a small number of customers clearly a larger handover to support 1Gbps plans simply doesn't stack up. Orcon, like a number of other RSP's don't provide Gigabit in every UFB area.

99.9% of UFB customers aren't going to notice a real world difference between 200/200 and 1Gbps. If you are in that 0.1% my suggestion would be moving to a RSP who does offer it.
