Earlier quoted context omitted.
I currently use NameSilo. Don't forget they also offer free whois privacy for life. My only complaint with them is their DNS records are only updated once every 15 minutes. This makes doing automated API based DNS based LE challenges annoying because you need to sleep your script for 15 minutes to ensure the update got pushed. Also, I'm surprised Cloudflare omit talking about whois privacy in the blog post. Makes me…
We actually didn't talk about WHOIS Privacy because it's becoming less and less of a relevant feature in the post-GDPR world. We do support it, free of charge. Cloudflare is also the largest authoritative DNS deployment in the world, and changes propagate in closer to 15 seconds than 15 minutes.
Do you happen to also offer free email forwarding with registered domains?
