I’m hoping this helps others in identifying slower dns resolvers so they can switch to a speedier provider. How does it work?

TL;DR: My www.domainname.com address works as intended, but domainname.com redirects to an unauthorized website. How can I fix this? I host my business domain through Cloudflare.
