No idea what caused it to break but for now I'm happy just to have a working system!
The only place I have my DNS server's IP set on my systems is in the Network Manager configuration, and that only on ones with static IP.
This server has been through a number of OS upgrades so it's a mixture of historical configurations and current ones.
However, I did an update on another server, and it pulled in an updated version of resolved.conf, offering the choice to replace my installed copy. Accepting it wiped my DNS settings (although I was ready for that and added them back). So although I don't recall having blindly accepted an updated config on the first server I assume that's what I must have done.
