A company operates a high-traffic website with a backend service deployed in a primary AWS Region and a disaster recovery (DR) Region. They use a single Amazon CloudFront distribution for the website and have set up an Amazon Route 53 record set with health checks and a failover routing policy for the primary Region's backend service. This Route 53 record set is configured as an origin for the CloudFront distribution, with another record set pointing to the DR Region's backend service endpoint as a secondary failover. Both record sets have a TTL of 60 seconds. However, failover currently exceeds 1 minute. A solutions architect is tasked with designing a solution to minimize failover time. Which solution would achieve the fastest failover?
