    Global Accelerator:FAQ about endpoint groups

    Last Updated:Apr 02, 2026

    Can I use GA if my origin servers are in an unsupported region?

    Yes. When configuring the endpoint group, select the region nearest to your origin servers. GA forwards requests to the optimal endpoint in that group.

    How do I view the endpoint group IP addresses of a GA instance?

    1. Log on to the GA console.

    2. On the Instances page, find the GA instance and click Configure Listeners in the Actions column.

    3. On the Listeners tab, find the listener and choose > View Endpoint Group in the Actions column.

    4. On the Endpoint Group tab, find the endpoint group. The public IP addresses of endpoints in the region are shown in the Endpoint Group IPs column.

    Note

    The system assigns at least four public IP addresses to each endpoint. The number of IP addresses varies by billing method:

    • Pay-as-you-go: CIDR blocks or IP addresses are added or removed based on traffic fluctuation.

    • Subscription: IP addresses are based on instance specifications. When you modify instance specifications, IP addresses may be added or removed. Added IP addresses enter the Available state only after you confirm the specification change in the GA console or by calling the UpdateAcceleratorConfirm operation.

    To query public CIDR blocks or IP addresses programmatically, call ListEndpointGroups or ListEndpointGroupIpAddressCidrBlocks.

    What endpoint types does GA support?

    Supported endpoint types depend on your GA instance type and where your backend is deployed.

    Instance type Deployment Endpoint type
    Standard GA instance Alibaba Cloud ECS, ALB, NLB, CLB, OSS, ENI, Custom private IP address, Public IP address provided by Alibaba Cloud, vSwitch (custom routing listeners only)
    Outside Alibaba Cloud Custom public IP address, Custom domain name
    Basic GA instance Alibaba Cloud ENI, ECS, CLB, NLB
    Note

    • If your standard GA instance does not support ALB instances, ECS instances in VPCs, CLB instances in VPCs, NLB instances, or ENIs as endpoints, your instance may be an earlier version. Contact your account manager to upgrade.

    • To accelerate Alibaba Cloud backend services not supported by GA, or services in data centers, over private networks, add endpoints of the Custom Private IP Address type.

    • Basic GA instances support secondary elastic network interfaces (ENIs), Classic Load Balancer (CLB) instances in virtual private clouds (VPCs), internal-facing Network Load Balancer (NLB) instances, and Elastic Compute Service (ECS) instances. These resources cannot be associated with static public IP addresses or elastic IP addresses (EIPs).
