I did something very similar a while back: https://mbrizic.com/blog/solarhosting/

What did you use to differentiate green from (I'm guessing) blue links when it's down?

Each color is a different build running on a different server. And then a load balancer picks which server you'll end up on.

Code-wise, the only difference between the builds is the CSS setting the link color.
