The following table lists the default thresholds at which Anti-DDoS Origin Basic automatically triggers blackhole filtering in each region.

Note
  • Anti-DDoS Origin Basic automatically triggers blackhole filtering for Elastic Compute Service (ECS) instances, Server Load Balancer (SLB) instances, elastic IP addresses (EIPs), and Web Application Firewall (WAF) instances. This feature is available for IPv4 networks in all regions and for IPv6 networks only in specific regions. In the following table, a check sign (√) in the Support IPv6 column indicates that the automatic blackhole filtering triggering feature is supported for IPv6 traffic in the region and the thresholds are applicable to both IPv4 and IPv6 networks. A cross sign (×) indicates that the feature is not supported for IPv6 traffic in the region and the thresholds are applicable only to IPv4 networks.
  • In practice, the thresholds to trigger blackhole filtering for ECS instances, SLB instances, and EIPs vary based on the instance type and bandwidth that you purchase. For more information, go to the Assets page of the Anti-DDoS console for more details. For more information, see Assets
  • In each region, the same threshold to trigger blackhole filtering is applied to WAF instances, SLB instances, and EIPs.
