dns

This skill should be used when the user asks about "DNS", "domain resolution", "GeoDNS / geo routing", "latency-based routing", "weighted / failover routing", "Route 53 / Cloud DNS", an "A/CNAME/ALIAS record", "anycast", or "DNS TTL / propagation". It gives the global front door that maps a name to the right IP and steers users to the right region or endpoint. Use it whenever a design must direct traffic across regions/data centers, do health-checked failover at the name layer, or expose a stable hostname even if the user doesn't say "DNS".
