Question

How can I protect my CDN domain that is under Distributed Denial of Service (DDoS) or HTTP flood attacks?

Answer

When a CDN domain is under DDoS or HTTP flood attacks, CDN automatically runs the CDN domain in a sandbox. In the sandbox, the CDN domain is still available, but the service performance may be downgraded.

If your CDN domain is vulnerable to DDoS or HTTP flood attacks, we recommend that you use Secure Content Delivery Network (SCDN).
Note Currently, SCDN is only supported in mainland China.
