Strange CNAME flattening


I have created a CNAME record for Kinsta.

You can see it here. But on that record, I get a message that there is another record with the same name, and CNAME flattening is enabled. Does anyone know what other records cause this issue because, for me, it looks like there is no interfering record?

I’ve seen that before for a Cloudflare Tunnel CNAME, but I don’t think anything was actually broken. Just a false alarm.

At the domain Apex, it’s the SOA.

Ah, now I remember. Yes, I do see this in my Tunnels.

RFC rules say you can’t CNAME a domain root, so Cloudflare flattens that CNAME. It’s just a FYI.
