CIRA was removed 4 years ago: https://github.com/DNSCrypt/dnscrypt-resolvers/issues/442#issuecomment-797488366

Did they manage to fix their servers since?

In the description, can you clarify what "private" and "protected" mean?

It's basic DoH without anonymization, so "private" may be confusing.

I think so - I've been using it via the cloudflared dns-proxy for the past year with no issues!

Updated the descriptions. Let me know if that is sufficient

Can you include the certificate hashes?

Can you include the certificate hashes?

I was looking around for those and wasn't sure how to get them - would a site like this be all that's required? IE: put the URL resolver and then put the hashes into the stamp tool?

https://dnschecker.org/ssl-certificate-examination.php

[Edit] for example from that page, these are the hashes:

See https://github.com/DNSCrypt/doh-server?tab=readme-ov-file#dns-stamps-and-certificate-hashes

But not a big deal, I will add them.
