Kevin - Failover best practice

New About Yours API Help
516 bytes, Plain text
Big fan of the show. I want to run a website with failover or loadbalancing, particularly, so I can take one node offline for updates and the other will continue to serve traffic. I don't want to be tied to one VPS provider or OS. I currently have OpenBSD 6.3 on Vultr and Fedora 28 on DigitalOcean. Can this be done at the DNS level? What's the difference between Round Robin DNS and Anycast DNS? What is a good primary or secondary DNS provider who supports these and DNSSEC?

Thank you for all your work!
