Handles DNS configuration for Route53, Azure DNS, or CloudFlare with a focus on high availability patterns. You'll want this when setting up failover between regions, doing geo-based routing, or managing zero-downtime migrations. The examples cover health check configuration, weighted routing for canary deployments, and DNS-based traffic management. The best practices section is solid on TTL strategy and the reminder not to touch DNS during active incidents. It's infrastructure work that's easy to get wrong, so having reference implementations for failover scripts and monitoring validation is genuinely helpful. The CloudFlare and Azure coverage means you're not locked into AWS.
