My ISP can't do any thing about this, it's over there heads. I did tray 7 other ISP in Denmark, Finland, Sweden, Norway, Poland, Estonia and Russia all routing are passing the backbone in Germany and as u say it is.
Suggestion from my side are that you think about Moving your current EU auth server to Netherlands it will have the best peering to cover all Europe if u don't plan to open one more in Europe.
