But still one of the biggest reason why I don't use Quad9 is query time compared to rest (1.1.1.1 and 8.8.8.8), query time seem to be okay on the central EU area (where 99% clusters are), but not on Northern EU area.
Quad9 support told a week ago, that Sweden is about to get their cluster, in this or next month. Estonia has their cluster since last year, but it doesn't help much in Finland, Sweden or Norway. They also replied that they are working on cluster for Finland, but didn't gave any ETA.
