AWS Gateway Load Balancer Gains TCP Reset Support for Faster Failure Recovery

AWS Gateway Load Balancer (GWLB) now supports sending TCP Reset (RST) packets when a target becomes unhealthy, is deregistered, or a flow's idle timeout expires. This enhancement reduces traffic interruption times from minutes to seconds by enabling TCP endpoints to quickly detect failed connections and establish new flows through healthy targets. The feature is not enabled by default for backward compatibility and can be configured per target group using the AWS Management Console, CLI, or API. It is available in all AWS Regions where GWLB is offered, with no additional charge.
