Would you make a recommendation of running unbound on the local exit nodes to resolve local DNS server congestion to get around this issue?
Thanks,
Conrad

first of all thanks for running exit relays!
One of the crucial service that you provide in addition to forwarding TCP streams is DNS resolution for tor clients. Exits relays which fail to resolve hostnames are barely useful for tor clients.
We noticed that lately the failure rates did increase again and would like to urge you to visit Arthur's "Tor Exit DNS Timeouts" page that shows you the DNS error rate for exit relays:
https://arthuredelstein.net/exits/ (the page is usually updated once a day)
Please consider checking your DNS if your exit relay consistently shows a non zero timeout rate - and make sure you run an up to date tor version.
If you are an exit operator but have no (or no working) ContactInfo, please consider updating that field in your torrc so we can reach you if something is wrong with your relay.
kind regards nusenu
