A company initially hosted a static website on an Amazon S3 bucket accessible via example.com, utilizing an Amazon Route 53 weighted routing policy with a TTL of 1 day. They have now transitioned to a dynamic web application, fronted by an Application Load Balancer (ALB) directing traffic to a fleet of Amazon EC2 instances. To facilitate this transition, an additional Route 53 weighted DNS record was created, pointing to the ALB with a weight of 255 and a TTL of 1 hour. Despite these changes, the static website content occasionally appears when customers visit example.com. What action should a DevOps engineer take to ensure that only the new dynamic content is served from example.com?
