In my site www.doctoranytime.com.br visitors get randomly 1016 Origin DNS errors. I cannot reproduce them and they are not continuous. I checked related documentation and posts but nothing seems to apply here since the errors happen randomly.
Site’s DNS is not on Cloudflare, it is partner hosted. (I am also the DNS host).
Most likely cause: The DNS server responsible for the CNAME record representing your origin periodically fails to resolve when Cloudflare attempts to resolve the target for your requests.
Sounds like you are ina partner setup so that’s your hosting provider’s DNS infrastructure.
