ICP filing

The Alibaba Cloud international site (alibabacloud.com) uses domain registrars outside the Chinese mainland, so domain names registered on the international site are not eligible for ICP filing. To deploy services in the Chinese mainland, register the domain name on the Alibaba Cloud China site (aliyun.com) and complete the ICP filing. Otherwise, your services may be inaccessible from the Chinese mainland.
