Many users experience sudden latency spikes, severe packet loss, or even inaccessible websites when using US VPS services during peak hours. The root cause is often congestion at the international gateways of standard 163 routing. In comparison, US VPS services with triple-network CN2 routing offer better cross-border transmission paths, effectively reducing network latency and packet loss.

So, how should you choose a US CN2 VPS? When selecting a US CN2 VPS, you need to understand the differences between CN2 GIA, CN2 GT, and standard 163 routing. Prioritize CN2 GIA with optimized routing in both directions, and verify the actual route quality through traceroute tests to avoid being misled by promotional claims for low-cost CN2 VPS services.
CN2 GIA, CN2 GT, and standard 163 routing are three common network options for US VPS services. Their main differences lie in transmission paths, routing priority, and network stability during peak hours.
CN2 GIA: China Telecom's premium network. Both outbound and return traffic are routed through the CN2 GIA network, providing better routing quality and greater stability during peak hours.
CN2 GT: A standard optimized CN2 route. Typically, only some international gateway segments use the CN2 network, while domestic traffic may still pass through the 163 backbone network. Its network performance and pricing generally fall between CN2 GIA and standard routing.
Standard 163 Routing: China Telecom's traditional backbone network (AS4134). It offers lower costs and broad coverage, but its international gateways are more susceptible to congestion, increased latency, and packet loss during evening peak hours.
A US VPS with triple-network CN2 routing is a server hosted in the United States with optimized network routes for China's three major telecom carriers: China Telecom, China Unicom, and China Mobile. It offers low latency, low packet loss, and high network stability.
With so many US VPS products on the market, how do you choose the right one? Below, we recommend a reliable US VPS with triple-network CN2 routing to save you the hassle of extensive research and testing.
VMRack is a provider specializing in global cloud infrastructure services. Its offerings include cloud servers, bare metal servers, CDN acceleration, cloud transcoding, and a range of other products and solutions.

In terms of network connectivity, VMRack has implemented dedicated routing optimizations for China Telecom, China Unicom, and China Mobile. It offers premium cloud servers with optimized routes for all three carriers, aiming to provide users in China with faster and more stable cross-border connectivity.
China Telecom: Uses the premium CN2 GIA network to optimize cross-border transmission paths, effectively reducing access latency and improving network stability during evening peak hours.
China Unicom: Connects to China Unicom's premium CUII backbone network, offering lower network loads and excellent transmission performance for faster and more stable access.
China Mobile: Uses China Mobile's next-generation premium backbone network (CMIN2) to optimize international routing, reduce network congestion, and further improve cross-border connection speeds and stability for China Mobile users.
What's more, VMRack operates its own data center in Los Angeles, USA. Unlike providers that rent space in third-party data centers, VMRack maintains full control over its servers, network infrastructure, and IP resources.
VMRack also supports custom VPS plans, allowing users to flexibly select CPU, memory, storage, and bandwidth configurations based on their specific business requirements. You only pay for the resources you need, helping avoid unnecessary resource costs.
Standard US VPS services are prone to high latency and packet loss during evening peak hours, which can even prevent users from connecting to their servers via SSH. In contrast, US VPS services with triple-network CN2 routing leverage premium networks such as CN2 GIA, AS9929, and CMIN2 to significantly improve network stability. If you're looking for a high-quality US VPS with optimized routing for all three major Chinese carriers, consider VMRack's premium cloud servers.
