Lemmy.ca Support / Questions

Approx 30 mins ago, I suddenly lost access to lemmy.ca due to DNS resolution failures. I've managed to restore access by tossing the known good IP into my computers hosts file, in order to make this post.

It's worth noting I'm running my own DNS resolver (via PfSense router/firewall software) instead of the typical DNS forwarder offered by my ISP. As a result, my DNS ecosystem is likely a bit more fussy about the "correctness" of the DNS configuration.

My DNS server logs some entries complaining about DS and DNSKEY

debug: Failed to match any usable DS to a DNSKEY.
info: Could not establish a chain of trust to keys for lemmy.ca. DNSKEY IN

An attempt to verify the domain name using delv results in the following:

delv lemmy.ca 
;; broken trust chain resolving 'lemmy.ca/A/IN': 127.0.0.53#53
;; resolution failed: broken trust chain

Running an external DNSSEC check tool, currenly reports DNSSEC related issues. The tool I ran was:

https://dnssec-analyzer.verisignlabs.com/lemmy.ca

This gave me two issues:

None of the 2 DNSKEY records could be validated by any of the 2 DS records

The DNSKEY RRset was not signed by any trusted keys

Did something related to DNS get deployed in the last little while?

In any case, I've got a workaround in place and am not stuck, however a site admin may want to be aware of this information.

Thanks!!
