I did see that post, and I think we reasonably meet all the requirements.
The two servers I mentioned do technically log, in the sense that they cache queries and responses in a redis database for performance across all nodes, but that seems like a reasonable limitation and all logs are anonymized (no user data retained).
We also have DNSSEC, but not using the default trust anchors (like I mentioned in my other post).
I really don’t think these are major issues (especially if you’d be willing to work with us on DNSSEC), since it’s essentially impossible to find a DNS server that doesn’t log in some form (caching). If they are, let me know, and I’ll see if we can work something out.
I personally think it’d be beneficial for you to start endorsing open-source services with aligned values vs servers from the likes of Google, OpenDNS, etc.
