> never use abbrevations like SS, NS, AH, HH, HJ in Germany

Very true, also for Austria. When I was in the military and we got our Steyr AUG A1 we had to know the serial number by heart so we could find our gun when mixed up. We also had to report our serial number when asked by instructors. Mine started with "HJ18" which was by random chance but always wondered why these wouldn't be taken out before production because of the obvious nazi code

It seems unfortunate if Kazakhstan has been assigned a TLD that makes it hard for them to do business with Germany.

When you are operating out of Kazakhstan, I'm sure Germans get the context. It's different when you're actively choosing the name.
