Should be easy enough. But, the problem is the scale. I work at a privacy conscious EU based startup and we used to use quad9 for our infra. Shortly after we started using, we started to hit scalability issues. When the whole eu traffic was hot, our DNS query latency would also go up. To be able to keep up, we had to switch back to CF and Google. Hope there is a really good alternative one day.
