I am setting up a failover solution but I have no idea how to do it. I need help please.
Here is my condition. I have 3 dedicated servers. Each of the server having 2 domains pointing at it. There are total 6 domains. All servers have the backup of the other websites.
I would like to setup that when one the the server is down. It will automatically switch to other server with zero down time. I think adding 3 A records in DNS is not working, right? I took a look on this article but still have no idea what should I do. https://www.cloudflare.com/zh-tw/learning/performance/what-is-server-failover/
I would like you experts to help me a bit. Sorry for asking the stupid question. I am new in website development. Thank you guys in advance.
