How is the recommended TTL calculated?

The `calculate_ttl_and_failover` tool ensures the recommended TTL is less than or equal to the detection window (health check interval multiplied by the failure threshold).

Can I calculate weighted traffic distribution?

Yes, use the `calculate_routing_distribution` tool by providing an array of numeric weights to see the exact percentage of traffic for each resource.

What routing types are supported?

The server supports calculations for active-passive, active-active, latency-based, weighted, and geolocation routing strategies.

More Details Connect to Claude

Optimize your AWS DNS configuration with precise calculations for Route 53. This MCP server provides tools to determine the ideal Time to Live (TTL) based on your health check intervals and failure thresholds. Use calculate_ttl_and_failover to predict total failover time and propagation delays, ensuring your high-availability strategies like active-passive or latency-based routing are mathematically sound. You can also use calculate_routing_distribution to manage weighted traffic splits and get_routing_metadata to retrieve AWS region and geolocation hierarchy details.
