Ahh, return routes...

Your traffic to Pacific does go through WAIX however the traffic back
(your downloads) may go through whatever link pacific's servers think is
Pacific's "WAIX" link is notorious for routing back as non-WAIX traffic,
something that comes up once a month on the Whingepool Amnet forum :P

Check with Pacific's Looking Glass tool to see how it'd be routed

ISPs that are HQ'd in Perth are likely to be pushing all they can
through WAIX cos it's cheap(er*).
Besides, debian repositories are in Perth... what else do you need? :P
I've heard people set their DNS to iiNet's to increase the likelihood
Microsoft Update & Downloads, iTunes & Previews, Adobe downloads, ABC
VODcasts all end up coming through the iiNet/Akamai mirrors.
Personally, in *really* dire circumstances, I'll set my firewall to only
allow torrent traffic from WA ISPs, and once it's finished downloading,
reset it to allow all internet traffic (since uploads are still free)

Yes, and I feel your pain...
