What Should I Do If Access to a Client Is Denied Due to DDoS Attacks?
You can use the view the anomalies of a single public IP address within the last 24 hours in the monitoring report, or view the protection statistics of all public IP addresses, such as the Top 10 attacked public IP addresses in the interception report, to determine whether the access to a client is blocked due to the black hole triggered when your services are under DDoS attacks.
The system automatically deactivates the black hole 24 hours after the access to a cloud server was blocked due to the triggered black hole.
