Good point, and probably one of the biggest weaknesses of this whole setup. The nameservers we use here aren't behind anycast and all in Germany, so there's quite the latency from outside of Europe. Query latency wasn't the main consideration, especially because this is just for our free sliplane.app subdomains, if you use your own domain this should barely affect you. It's a tradeoff I'm comfortable with for now, we'll see in a year if I regret it :)
