How about Hong Kong CN2 pure international high-defense line? Regarding the lines of Hong Kong servers, we usually come into contact with three categories, namely pure international lines, return lines and Hong Kong local lines. There is a price difference between the three, the reason is reflected in the line and network quality, of course, these will be related to the speed and stability of the server. Hong Kong CN2 host is the host of Hong Kong cn2 line, located in the Hong Kong CN2 line computer room, very close to the mainland, so mainland users can access it very quickly.
　　If mainland users want to seek access speed, it is recommended to rent Hong Kong CN2+BGP line. CN2 line accesses Telecom faster, while BGP protocol can be accessed directly by different lines such as Mobile and Unicom, so the speed will be more advantageous. The following will introduce the three lines of CN2/pure international/high defense of Hong Kong servers to help readers better understand their characteristics and advantages.
　　1. How about Hong Kong boutique CN2 line host?
　　1. When choosing a Hong Kong server, CN2 direct to China line is a highly respected choice. The most significant advantage of Hong Kong CN2 host using CN2 line is good access speed and good stability. Since the CN2 line accesses China Telecom's dedicated line, it is much faster than ordinary lines, with low latency, low packet loss rate and high security.
　　It is the next-generation bearer network launched by China Telecom. Compared with traditional bandwidth lines, it has better quality and performance. It connects China and Hong Kong, China Telecom (CT), China Unicom (CU) and China Mobile (CM) in a direct connection. When returning to China, they all take their own lines. Since there is no need for cross-line switching, the latency is the lowest.
　　2. Since CN2 carries SLA services with QoS guarantees, and in order to meet the QoS requirements of the carried services, CN2 provides high-performance network indicators. Therefore, using Hong Kong CN2 hosts can increase the flexibility and scalability of the company's business. The biggest advantage of Hong Kong CN2 host over other domestic lines is that it solves the problem of data exchange between different ISPs, and the problem of network access between China Telecom, China Unicom, China Mobile, etc., so it is faster and more stable!
　　2. Pure international line Hong Kong server
　　The international BGP link mainly accesses PCCW/BTN, Mzima, Level (3), Global Crossing, Sprint, Savvis and other links. This link mainly covers overseas regions such as Asia, Europe and the United States outside the mainland, and is more suitable for websites facing international users. When using international lines, it means that no matter where the user is in the world, he can access and use Hong Kong servers. This provides users with broader network resources and more convenient service experience. However, due to factors such as geographical distance, there are detours when using pure international lines to return to China, which may cause a certain degree of access speed reduction.
　　After choosing a pure international line, some users said that they encountered slow speed and poor stability of Hong Kong servers. First of all, we cannot deny that the regular and normal Hong Kong servers have the characteristics of high stability and speed. However, due to some factors, the stability of pure international lines will be affected.
　　3. High-defense line Hong Kong server
　　High-defense line refers to a technical means of attack protection and security detection of the server through a series of security measures. It can effectively identify and filter malicious traffic to ensure the security of network assets. This line has strong defense capabilities and can effectively resist network security threats such as DDoS attacks. Of course, for safety, after the Hong Kong server is opened, you can apply for more bandwidth or DDoS protection.  
　　Normally, for users who need to take international routes for foreign trade business, choose pure international lines. The bandwidth of this type of line is relatively large, and international users will have smoother access and lower prices. It’s just that for mainland users, the access will have high latency and high packet loss rate, and poor stability. In fact, in this case, we can consider other types of network lines.
　　For example: customers whose business is mainly in Hong Kong can choose a local LAN; users whose customers are mainly in mainland China can choose CN2 GIA routes or CN2+BGP hybrid lines. You can refer to Hengchuang Hong Kong server, which uses high-speed direct connection CN2 GIA lines, which can provide low latency for national access, and even as low as 10ms network experience in coastal cities.
　　The above is an introduction to the Hong Kong server line. Many large international computer room service providers will choose to set up computer rooms in Hong Kong, which is much more convenient and faster for users who want to do foreign trade business. However, when choosing a Hong Kong server, users need to comprehensively consider their own needs and budget and choose the type of line that suits them. If the customer base is concentrated in China, it is recommended to use a Hong Kong server connected to the CN2 line; if the customer base is concentrated overseas, you can choose a Hong Kong server with a purely international line; if enterprises and organizations that require high defense capabilities, you can choose to use a high-defense line.
