IPv6 brokenness in Norway

[Eric Vyncke (evyncke)]

Tore

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

> Norwegian ISPs that provides IPv6 to end users.

> very clearly visible in the graphs.  At the moment there's so few users
> of older broken Opera versions that the brokenness they cause is barely
> distinguishable from statistical noise.

> - Mac OS X is currently the biggest contributor to the brokenness, by
> far.  The brokenness percentage drops by 70-80% when disregarding all
> hits from Mac OS X.  As I've noted earlier, a fix for this is likely to
> be included in OS X 10.6.5 which is currently available in beta
> versions.  I doubt, however, that (close to) all OS X related brokenness
> will vanish overnight - there are still many users of OS X 10.4 and 10.5
> out there who won't be able to install the update.
> Nevertheless I'm certain that the release of 10.6.5 will have a positive
> impact, and it will be exciting to see exactly how large.

> 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.
