Latley ive been getting 150+ ping on the OZ server and 200+ ping on ga7. I know that Fodder has the same problem and hes also based in NZ with Telstra as his isp. Just wondering how i should go about getting this fixed?
All you can do is phone them and see if they are doing something to your line.
Being Telstra, nothing will probably be done about it unless they are currently upgrading something and are routing you a different way while these things are being done.
Do you have a wireless router and or multiple computers on the same network? Have you recently installed a new anti-virus program/similar program that has its own acces to the net?
It could also probably be something with your ISP, like upgrades so you're connection is being re-routed or whatever
