Using Cloudflare as mirror/backup instead of main domain?

Question

Based on what's currently happening with "false positive" bans [0] being automatically issued for flagged payment methods [1], I'm thinking on using Cloudflare for mirror or backup domains only, and let users know if the main site ever goes down to use CF's instead. It's easy to automate this redirection from an app, are there any browser extensions that can help with this?[0]: https://news.ycombinator.com/item?id=31574702 [1]: https://news.ycombinator.com/item?id=31575361

afaik: cloudflare redirects the stuff for your domain xyz.com to the servers using dns. so instead of xyz.com pointing to 10.0.0.1 cloudflare dns server says that xyz.com is on 172.16.0.1. the cloudflare webserver them gives then the request to the real webserver behind it.
