A TCP service runs in multiple Regions.
Give clients fixed IP addresses and exclude an unhealthy endpoint automatically.
Which service is most appropriate?
Use AWS Global Accelerator with static Anycast IPs and endpoint health checks.
Detailed explanation

Foundation review
DNS versus network entry
Global Accelerator preserves fixed IP entry points; DNS routing changes name answers.
Regional failover
Health checks can steer new connections away from an unavailable Region.
