Notice content

To improve the accuracy of DNS resolution, Public Authoritative DNS Resolution of Alibaba Cloud DNS will start to optimize resolution lines in phases from 00:00:00 on November 5, 2024 (UTC+8). This process may last for 30 days. 

After the phased optimization starts, resolution results obtained by some of your end-users may change when they access your domain name. You must add a resolution record whose resolution line is set as “default” to your domain name. Otherwise, network users may fail to obtain the resolution results when they send requests to resolve the domain name, because no matched resolution line is available. 

After the optimization is complete, more resolution line settings for Public Authoritative DNS Resolution are available in the Alibaba Cloud DNS console. This meets your requirements on more fine-grained scheduling of resolution lines.
