I got lots of "[WARN] eventdns: All nameservers have failed" with my own DNS server. With the 4 DNS servers I posted here a few minutes ago, I never saw this warning again.
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: https://trac.torproject.org/projects/tor/ticket/23113
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).
