## Description

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.

## Tools

### calculate_routing_distribution
Determines the traffic split for weighted routing configurations

### calculate_ttl_and_failover
Calculates optimal TTL and expected failover time for Route 53

### get_routing_metadata
Provides structural context for geolocation and latency-based routing strategies

## Prompt Examples

**Prompt:** 
```
Calculate the TTL and failover time for an A record with a 10s health check interval and a 3 failure threshold using active-passive failover.
```

**Response:** 
```
The recommended TTL is 30 seconds. The total failover time is 60 seconds, and the estimated propagation time is 60 seconds.
```

**Prompt:** 
```
What is the traffic split for weights [10, 30, 60]?
```

**Response:** 
```
The traffic distribution is 10%, 30%, and 60% respectively.
```

**Prompt:** 
```
Get the hierarchy for geolocation routing.
```

**Response:** 
```
The geolocation hierarchy is Country, Continent, and Default.
```

## Frequently Asked Questions

**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.
