anatoki: As I said in the other thread, it's a problem with 1 particular host so I'd hazard a guess and say the problem is with FairFax Media and not TelstraClear. It may be worth logging a fault with TelstraClear if you really are concerned (and really want to see all those ads they're trying to serve you!).
I've tried from a couple of other computers that are not on TCL and they show the SMH website fine. I guess it could be something fairfax have got wrong, but if other ISPs have their networks configured to avoid the problem, then it points to TCL not caring about their customers' experience.
But then again, I've not really got a problem with it because I have a workaround and have posted it here on geekzone a couple of times so anyone with google-skills will be able to figure it out.
