This topic introduces sandboxes and their features and describes impacts on domain names that are in a sandbox.

What is a sandbox?

A sandbox is a set of special nodes for Alibaba Cloud CDN. The nodes are isolated from regular nodes. After an accelerated domain name is added to a sandbox, the CDN service is not guaranteed, and the domain name may be unavailable for a period of time.

When will a domain name be added to a sandbox?

Alibaba Cloud CDN provides content delivery for thousands of accelerated domain names. If an accelerated domain name is under attack, Alibaba Cloud CDN has the right to add the attacked domain name to a sandbox based on factors such as the service status of the domain name and the impact of the attack. This ensures that the CDN service of other users can work as expected. If the accelerated domain name is under severe attack, other accelerated domain names in the same Alibaba Cloud account are also added to the sandbox.

What can I do if my accelerated domain name is added to a sandbox?

By default, Alibaba Cloud CDN does not provide protection against attacks. After an accelerated domain name is added to a sandbox, the CDN service is not guaranteed and the domain name cannot be removed from the sandbox. You can choose DCDN Edge Security or Anti-DDoS Pro or Premium based on your business requirements.
Notice
  • Alibaba Cloud CDN reserves the right to disable the acceleration service for domain names that are frequently attacked and for domain names that are attacked due to violations of the Alibaba Cloud CDN limits. If your domain name is under attack due to violations of the Alibaba Cloud CDN limits, Alibaba Cloud CDN does not bear any responsibility and all fees incurred are borne by you.
  • After an accelerated domain name is added to a sandbox, visits to the accelerated domain name continue to incur data transfer fees.
  • If the accelerated region of a domain name is outside the Chinese mainland and the domain name does not have an Internet Content Provider (ICP) number, the domain name becomes unavailable after it is added to a sandbox.

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

After an accelerated domain name is added to a sandbox, a notification will be sent to you through SMS. You can also log on to the Alibaba Cloud CDN console and check the status of the domain names.

Can I remove domain names from sandboxes?

To ensure that other users can use their CDN service as expected, you are not allowed to remove domain names from sandboxes.
