When the network traffic destined for a cloud service that is assigned a public IP address exceeds the specified traffic scrubbing threshold, Anti-DDoS Origin Basic automatically scrubs the traffic to protect your business from DDoS attacks.
For more information about traffic scrubbing, see Terms.
The traffic scrubbing threshold supported by each cloud service varies based on the instance specification of the cloud service. When you create or change the specifications of an Elastic Compute Service (ECS) instance, Server Load Balancer (SLB) instance, or NAT gateway, the system automatically calculates the traffic scrubbing threshold based on the current instance specification.
The system calculates blackhole filtering thresholds for instances of each cloud service based the regions in which the instances reside, the bandwidth of the instances, and the security credit score.
