I certainly wouldn't consider 140ms to Aussie to be on the good end. O_O
Well if I was in a totally unreasonable mood one could conciser any more then 30ms extremely bad latency and my ISP should be bending over backwards to give me the best service as I'm paying top dollar $120 per month.
30ms is almost the latency on the SSC between AKL <-> SYD any increased latency means my ISP is not giving me 1:1 bandwidth.
Also remember there is no SLA for latency to anywhere in the world.
I know that NZ is full with such l33t gamers that an extra 0.1 seconds reaction time causes you to lose all the time.
