Apr 30 2025
Server Load Balancer (SLB)Content
When a GWLB backend server is detected as unhealthy or is removed, new flows will be routed to other available backend servers. However, existing traffic may still flow to the unavailable server, which may cause packet loss. You can enable the Rebalance feature for the GWLB server group. When a backend server is unavailable, GWLB will reroute the existing flows to other available backend servers.
