China’s Internet architecture differs from the rest of the world. There are three major internet service providers (ISPs) that control the network inside of China—China Telecom, China Unicom, China Mobile. Due to limited interconnection (peering) between their networks, there is frequently congestion, which results in high latency and packet loss. Even within an ISP’s network across China (for example, China Telecom in Beijing and China Telecom in Guangzhou), the quality of the network can vary significantly. Thus, to optimize delivery of content throughout China, it’s important to have geographically dispersed data centers across China, and connectivity to the major ISPs in each region, which is what our China Service offers to our customers.
Cloudflare customers can turn on the China Network with a few clicks in their existing Cloudflare account, and without a single line of code change, enable their visitors within China to be served from data centers inside of China while visitors outside of China will still be served from the nearest Cloudflare data center. The result is shaving off seconds of latency for your China traffic. To illustrate the impact on your visitors’ experience, let’s assume one unique user makes 100 requests per session, you have 50,000 unique visitors per day, and turning on Cloudflare’s China Service reduces 200ms of latency:
The China Network is available for all Cloudflare Enterprise customers and turning it on takes only a few steps. Contact our Customer Success Team, and we’ll walk you through the steps below:
ICP is the short name for "Internet Content Provider". According to Chinese regulation, all website hosted in Mainland China or content served from Chinese data centers (which is true for our China CDN service) needs to obtain an ICP "BeiAn备案" or "License 证" number for every domain that serves content to your pages. These number needs to be displayed on footer of your pages.
Cloudflare does not offer a Chinese version our service, but our partner Baidu offers a localized version of our service called Yunjiasu (百度云加速). Yunjiasu offers the same features and functionality as Cloudflare (CDN, DNS, DDoS protection, WAF, etc), tailored for the China market. Please visit http://su.baidu.com/ for more information.
If you are an existing Cloudflare customer and wish to transition to Yunjiasu’s Mandarin language platform, please visit our knowledge base article on choosing Cloudflare or Yunjiasu for more information. Please note that a domain cannot be simultaneously active on both Cloudflare and Yunjiasu.
