When webmasters, developers or corporate users are choosing overseas servers, the two most common place names are: Hong Kong and Singapore. These two places with dense data centers, mature networks and open policies are recognized as the "golden springboard" for mainland China's business to go overseas or overseas business to return to China. If you are a project that is accessible to the mainland, such as a website, interface API, or video platform, which one is more suitable, the Hong Kong server or the Singapore server?

　　1. From the perspective of "physical distance" to see latency: Hong Kong wins

　　First, let me tell you a simple and rough fact: Hong Kong is closer to the mainland.

　　The physical straight-line distance from Hong Kong to Guangzhou, Beijing, and Shanghai is usually within 1.000 kilometers. Singapore is in Nanyang, across the entire Southeast Asia, and is nearly 4.000 kilometers away from Shanghai.

　　This means that the theoretical transmission distance from the mainland user terminal to these two computer rooms is three or four times different.

　　The result is also very direct:

　　Hong Kong server Ping value is generally 15ms~50ms

　　Singapore server Ping value is between 50ms~100ms

　　So if you are doing real-time business (video, voice, transaction, live broadcast) - choose Hong Kong, there is basically no second option.

　　II. From the "line type" to see the return: Hong Kong CN2 has obvious advantages, but Singapore also has surprises

　　Many people say that Hong Kong is fast because Hong Kong servers can choose CN2 GIA (high-quality optimized line). This is a high-speed channel designed by Telecom for high-end international customers. There is no detour, no jump, and low congestion when returning to China.

　　Hong Kong CN2 GIA: The delay to Beijing and Shanghai is stable at 20ms~40ms all year round;

　　Hong Kong ordinary BGP line: It may float between 40ms~80ms, depending on the operator congestion;

　　Singapore CN2 VPS also exists, but the cost is higher and the resources are less.

　　However, don't underestimate Singapore:

　　Some high-end Singapore VPS providers have also optimized CN2 backhaul or connected to BGP hybrid networks;

　　If you choose well, Singapore can also achieve a stable connection within 50ms when visiting the mainland.

　　Third, from the perspective of "bandwidth resources", stability: Singapore is more generous, Hong Kong is more expensive

　　No matter how fast the mainland access speed is, if the bandwidth is restricted, the experience will be greatly discounted. In this regard, the advantages of Singapore servers begin to emerge.

　　Singapore data centers generally provide large bandwidth, 50M, 100M, and even 1Gbps unlimited flow is common;

　　Due to geographical location and tight resources, Hong Kong servers are generally 30%-50% more expensive, and there are many cases of small bandwidth pipes, many of which start with 1M/3M as standard.

　　Therefore, if you want to do content distribution, video on demand, and large traffic interface services, Singapore is more cost-effective.

　　The server that really suits you is not "the fastest in theory", but "the most stable in your business". So back to the original question: "Which server is better for mainland China access, Hong Kong or Singapore?"

　　The answer is not unique, but: if you pursue extreme latency, live broadcast, and second-level interaction, then it is Hong Kong. If you want to run high-bandwidth business, SaaS platform, lightweight API or distribution service, Singapore is more flexible and practical.
