Interesting article. > Your browser is usually clever enough to use the working IP address if the other one is not working. I found this to not work well. Have you tested it? For me it took 1-2 minutes for Chromium to switch over to the second entry after it had loaded the page from the first entry once (with a white page and spinning spinner during that time); this is usually not acceptable for site visitors as they will get impatient and leave already after a couple seconds. What I'm using instead for a setup is multiple A entries in combination with active removal of down IP addresses from the response using e.g. Route53 health checks and 10-second TTLs.
