Hetzner DNS has been delaying many responses for 5 seconds, causing outgoing federation work to pile up, almost running into OOM before we noticed.
I don't know if were being throttled because federation makes a lot of requests. Anyway, using Cloudflare DNS seems to solve it.
Enable DNSOverTLS for this because we can.
