Exit relay keeps showing DNS timeouts

I run an exit node and I constantly get warnings in Nyx and Tor Metrics that my relay is seeing a number of DNS timeouts, from 1-3%. Any way to fix this? Do I need to change my DNS server? I’m using Cloudflare right now. I was using Flokinet and HE but that didn’t fix the problem.

Quite a few people are running into this, due to the low threshold for DNS timeouts. Here’s a discussion on the tor-relays mailing list and a suggested workaround: [tor-relays] General overload -> DNS timeouts - #12 by tor-relays
