Telecom DSL customers are offered a service called 'Jetstream Games', whereby they connect to the DSL network with a different username and password, and are allowed full rate, non charged traffic, but only to a small number of servers. This is provided for online gaming, so people can play without incurring huge bills. It was a good selling point for Jetstream in the early days, however being connected to the 'gaming realm' means you cannot access the normal internet.

More appropriate for us perhaps, is that master.jetstreamgames.co.nz (203.96.91.1) is one of the NewZealandLinuxMirrors - this means you can download Debian at up to 8mbit/sec, for free, even if you're only on a 128k/s JetStart account.
