　　Reliability: The upgrade and optimization of the CN2 line aims to improve the reliability of connection. This means less network interruption and better network performance.

　　Optimized access to mainland China: If your server hosting in the United States and your user or business need to establish a stable connection with mainland China, using the CN2 line can improve the quality of connection.

　　Reducing the risk of network congestion: The CN2 line usually has a low risk of network congestion, which means that it can still provide good performance during the peak period of the network.
