that over August 2014, Norway rose from roughly 2% to 4%, while Belgium rose
from 22% to 29%. But that's percentages, not per capita.
Norway's population is roughly 5 million, Belgium's 11 million. So a 2% rise
among 5 million people isn't likely to stimulate a 7% rise in a country with
more than twice the population.
But looking at the APNIC stats from August, they don't show the coordinated
EU kick - so now I'm wondering if it's an artifact of Google's measurement
Two months earlier, in mid-June, the Google graphs for most European countries
show an odd semi-outage, and from then, compared to the APNIC numbers, they
seem to *undercount* till mid-August, when they all rise together to again be
similar to APNIC's.
Certainly it's apples and oranges comparing APNIC and Google stats, but this
might suggest there wasn't really a rise in IPv6 in mid-August (as measured by
Google), but more of a correction to a previous undercounting. Interesting.
