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): https://www.vyncke.org/ipv6status/compare.php?metric=p&countries=be,de,lu,ro,cz,no - with high-IPv6 non-EU (BE left in for comparison): https://www.vyncke.org/ipv6status/compare.php?metric=p&countries=be,us,jp,pe,my 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 ...?
