This topic describes the concept of a sandbox and the related features and solutions for domains in the sandbox.

What is a sandbox?

Dynamic Route for CDN (DCDN) integrates the technologies that are used to accelerate the delivery of dynamic content and static content. When an accelerated domain name is under DDoS or HTTP flood attacks, the CDN system automatically adds the domain name to the sandbox. This allows you to ensure the same level of service for other DCDN users. If the attack is severe, other accelerated domain names under the same account are also added to the sandbox. After a domain name is added to the sandbox, the service may be temporarily unavailable for certain periods.

What is the effect after an accelerated domain name is added to the sandbox?

An accelerated domain in the sandbox can still be accelerated by DCDN, but the service may be compromised.

Can a domain name be restored after it is added to the sandbox?

No, a domain name cannot be restored after it is added to the sandbox. This ensures that the acceleration service of other domain names can work as expected.

How do I check whether a domain name is added to the sandbox?

The system automatically sends a Short Message Service (SMS) notification after your domain name is added to the sandbox. You can also log on to the DCDN console and check the domain status.

How can I resolve the issue after a domain name is added to the sandbox?

By default, DCDN does not provide protection against network attacks. After an accelerated domain name is added to the sandbox, the acceleration service is not guaranteed and the domain cannot be restored. You can purchase Secure Content Delivery Network or Alibaba Cloud Anti-DDoS Pro to meet your security requirements.
Notice
  • DCDN reserves the right to disable the acceleration service for domains that are frequently attacked and for domains that are attacked because of violations of DCDN use limits. If your domain name is under attack because it has failed to comply with DCDN use limits, DCDN does not bear any responsibility and all fees incurred are borne by you.
  • If you use a unfiled domain name whose acceleration region is outside China, the domain name cannot be accessed after it is added to the sandbox.
