When a Smart Access Gateway (SAG) device connects to Alibaba Cloud, the connection may become unstable if the Internet performance is poor. In this case, you can change the access point. SAG allows you to use cloud services in a more flexible and stable manner.
Background information
An access point connects SAG devices to Cloud Connect Network (CCN). After an SAG instance is associated with a CCN instance, the SAG devices that belong to the SAG instance are automatically connected to the nearest access points. You can change the access points based on business requirements. CCN provides a wide variety of access points on a global scale. The following lists the access points.
Area | Access point |

Chinese mainland | Xi'an, Wuhan, Shenzhen, Shanghai, Qingdao, Chengdu, Hangzhou, Beijing, Guangzhou, Nanning, Nanjing, Xiamen, Hohhot, Shijiazhuang, Chongqing, Guiyang, Kunming, Changsha, Zhengzhou, Shenyang, and Dalian |
Outside Chinese mainland | Frankfurt, UK, Kuala Lumpur, Singapore, Jakarta, Sydney, Tokyo, Seoul, Santa Clara, Virginia, Ashburn, and Johannesburg |
