Apparently this warning happens when you have one DNS server in response
to malformed requests (like ".foo.bar").

I would not be too concerned about it if it's followed by:
"[notice] eventdns: Nameserver IP:53 is back up"

We'll try to work out whats happening and downgrade the warning in these
cases:

For client privacy and performance, it's best to have a local cache or
caching resolver first in the list.

For reliability, it's best to have another two entries in the list on
unrelated infrastructure (for example, one at the ISP, and one
elsewhere).
