I am stuck on a possible implementation for a problem I am facing in AWS.

I have multiple websites that are hosted with S3 using CloudFront in us-east-1. If there is an outage in that region, I want to reroute traffic from those UIs to a website hosted with S3 using CloudFront in another region (just a basic error page, all UIs from us-east-1 need to be rerouted to the same one error page in the new region).

After doing research, I am seeing a lot of documentation for Route 53 DNS Failover handling. However, we don't use Route 53 for traffic routing, so I don't think these solutions apply for this particular problem. Does anyone have any advice on possible solutions?

Using CloudFront's Origin Groups feature, you can group the two S3 endpoints and configure the criteria for when CloudFront should failover to the secondary origin (e.g., 500-504 error). When you create your cache behavior, you'll use the Origin Group as your origin. Details: Optimizing high availability with CloudFront origin failover
