[systemd-devel] systemd-resolved continuously switching DNS servers

[Kai Krakow]

Hello!

Why is systemd-resolved switching DNS servers all day long? This
doesn't seem to be right...

Also, name resolving seems to be very slow. When I directly use these
name servers in resolv.conf instead of going through the stub resolver,
there are no slow-downs and these logs stop.
