IPv6 brokenness in Norway

Thanks for the additional explanations and for running this statistics and explaining how you do it.

Just tossing an idea in the air: several content providers are indeed reluctant to go direct with a AAAA for their site for the reasons below. 

Therefore, it would be useful if there was a web site such yours where any webmaster could go, register its customer name, copy & paste some code in their HTML pages and get detailed statistics about brokenness of its own audience after a couple of days.

In the same way as done by Andrew at http://testv6.stdio.be but with you measurement

> Nevertheless I'm certain that the release of 10.6.5 will have a positive

> One explanation for this is that the publicly run student dormitories
> tends to empty out then, and they are the single largest network
> contributor to the brokenness issue (currently accounting for about 35%)
> as they discard all 6to4 traffic in their firewalls, thus exacerbating
> the OS X/Opera problems significantly.  Several other enterprises and
> governmental networks do the same thing, but the student village network
> is much larger (in terms of end-user count) than any other 6to4-hostile
> network in Norway at the moment.
> That's all I could think of right now...
