DNS not always resolving

bbushvt opened this issue · 4 comments

So I've run into an issue and I'm not sure if its something I've not configured correctly or if its a bug.
This particular time (I've had the same issue with other DNS names), when I try and go to www.reddit.com I get a "Hmm. We’re having trouble finding that site." in the browser and from the command line (ping) it says (ping: www.reddit.com: Name or service not known)

The log has entries like this
{"level":"info","ts":1702770267.1026013,"logger":"role.dns","msg":"DNS Query","instance":"dns01","version":"0.7.0-a864f302","runtime":6,"client":"192.168.53.200","response":"NOERROR","queryNames":["www.reddit.com."],"queryTypes":["AAAA"],"answerRecords":["reddit.map.fastly.net."],"answerTypes":["CNAME"]}

So its getting the request, knows that its a CNAME, but doesn't resolve it any further. If I manually ping the CNAME record "reddit.map.fastly.net", I get a response and from the logs it finds the A records

{"level":"info","ts":1702770297.6442485,"logger":"role.dns","msg":"DNS Query","instance":"dns01","version":"0.7.0-a864f302","runtime":10,"client":"192.168.53.200","response":"NOERROR","queryNames":["reddit.map.fastly.net."],"queryTypes":["A"],"answerRecords":["151.101.1.140","151.101.65.140","151.101.129.140","151.101.193.140"],"answerTypes":["A","A","A","A"]}

After that, if I try and ping www.reddit.com, it resolves correctly and I see this in the logs:
{"level":"info","ts":1702770299.9097157,"logger":"role.dns","msg":"DNS Query","instance":"dns01","version":"0.7.0-a864f302","runtime":4,"client":"192.168.53.200","response":"NOERROR","queryNames":["www.reddit.com."],"queryTypes":["A"],"answerRecords":["reddit.map.fastly.net.","151.101.1.140","151.101.65.140","151.101.129.140","151.101.193.140"],"answerTypes":["CNAME","A","A","A","A"]}

Any idea if this is a bug or do I have some misconfiguration?

The Root Zone has this configuration:

There seems to be a bug in regards to CNAME stuff (especially after the recent CNAME fixes) in the memory and etcd handler, so for the time being disabling those works around this issue

How do you go about disabling them?

@bbushvt Remove them from the handler configs in your zone settings.
