freitasm: It appears the ISP was presenting the gzt with a *VERY OLD* version of the scripts used to show the message.
As I said in my Twitter, transparent proxies and caches are the plague in New Zealand Internet. ISPs should have better pipes or at least be intelligent on how they manage those things.
Maybe some kind of ISP working group is needed to examine and report on the issues and recommended practices and solutions.
A independent reporting mechanism for submitting user issues might also be useful.
