Try testing many of the open recursive servers with dnsperftest [1] to see if Quad9 stands out. not my repo

Also run it from other servers/VM's to compare and contrast if you can.

I tried in Usa and Italy, and quad9 there has fast performance, so the issue I experience is probably limited to queries from Germany (so I've updated the title)

Nice. If nothing else that gives a list of alternatives to use in the mean time and a way to tell when one could switch back to Quad9. 1000ms = time out.

Results from USA near Yellowstone National Forest:
