Dear Alibaba Cloud users,
Due to network adjustment, domain names and IP addresses that are used by Security Center are scheduled to be added on April 18, 2024 (UTC+8). In most cases, this does not affect your business. If you configured access control policies such as IP address whitelists and domain name whitelists, you can add the domain names and IP addresses included in the following table to the whitelists. Otherwise, the status of the Security Center agent may be not restored to online. The following table provides the domain names and IP addresses.
If you are unsure whether you configured access control policies and the Security Center agent on your server becomes offline starting April 18, 2024 (UTC+8), you can join the DingTalk group numbered 15695013520 to obtain technical support.
