Arthur's DNS exit scanner is detecting a high DNS failure rate on some of your tor instances:

Would be great if you could look into this.

Interesting. This affects only one of three exit relay processes, which are all on one machine and use exactly the same config (and a local unbound):

# diff /etc/tor/instances/0/torrc /etc/tor/instances/2/torrc 1,4c1,4 < Nickname sofia # sponsored name! < ORPort 77.247.181.162:443 < DirPort 77.247.181.162:80 < Address 77.247.181.162 ---

Nickname CriticalMass # sponsored name! ORPort 77.247.181.166:443 DirPort 77.247.181.166:80 Address 77.247.181.166

# cat /etc/resolv.conf nameserver 127.0.0.1 nameserver ::1

I used the opportunity to reboot the machine to install the latest kernel and upgrade Tor. Let's check again in a day or so if the problem persists.
