So far all the conversation I've seen about this has been on the eyeball
side. Has anyone looked into whether or not the content networks have
made changes (removing/adding AAAAs for example) that would be
responsible for the temporary skew?

Hi Éric,
I'm puzzled, not about the recent decline (and now near-recovery) but at the
odd 'kick' in the stats on Aug 17, mainly for Europe.
Compare Belgium and most of the high-IPv6 EU countries (for clarity I left a
couple out like FR and CH, but they have small kicks as well):

- with high-IPv6 non-EU (BE left in for comparison):

The US and Peru show small increments too, but certainly not like the EU
countries.
Looking closely, it appears something increased the measurements in Europe a
little on 13 Aug, then a lot on 17 Aug. Erik Taraldsen from Telenor Norway
said they'd been rolling out v6 since summer - but that sounds more gradual
than a sudden increment in mid-August. Any ideas ...?
Regards,
Kate

Subject: Google IPv6 measurements in Europe appear heading down...
For a couple of weeks, it seems that Google IPv6 measurements are
heading down mainly for Europe. For example, here is a link to a
presentation of the Google measurements for several European countries
and USA. There is a clear drop in the last days/weeks for European
countries but not for USA.
This includes a big drop for my country (BE) :-O and I have checked
with all Belgian ISP and they have no explanation as for them 'business
as usual'. Apnic also does not show such a big drop.
So, I am guessing either a 'bug' in Google measurements infrastructure
in Europe or could it be that the IPv6 latency to Google has increased
a lot so that Happy Eyeball prefers IPv4? Recent measurement of
dual-stack latency to www.google.com from several Belgian ISP gave 10%
slower over IPv6.
Any clue will be welcome
