For websites with a global audience, China remains a region that's impossible to ignore—yet notoriously difficult to optimize.

Many overseas website owners run into the same issues:

Your server isn't in China, and worldwide access is fine, but loading speeds in China are painfully slow.

You’ve integrated a global CDN, only to find it does little to improve access from mainland China.

Worse yet, during attacks, your international CDN may fail entirely on Chinese networks.

The root cause isn't technical capability—it's the fundamental differences in network infrastructure.

CDN acceleration for China isn't just about having nodes there. It involves a complete system of intelligent routing, ISP interconnectivity, security architecture, and more.

In this guide, we’ve selected 5 CDN providers that excel specifically in the China region, helping global site owners make an informed choice.

How We Evaluated

Our ranking focuses on the following criteria:

1. Long-term experience and specialization in Chinese networks
2. Proven ability to optimize access from mainland China
3. Global accessibility and cross-border reliability
4. Service stability and long-term sustainability
5. Product maturity and customer support

This isn’t about who spends the most on ads—it’s about who actually solves the problem.

Frequently Asked Questions (FAQ)
Q1: What's the main difference between a China-optimized CDN and a regular global CDN?
A: Most global CDNs struggle to optimize access from mainland China. China-optimized CDNs have local nodes, BGP or dedicated line optimizations, resulting in much more stable and faster access.

Q2: Does an overseas website really need a China-specific CDN?
A: If more than 10% of your visitors are from China, yes—slow load times directly hurt conversions and retention.

Q3: Do all China CDNs require ICP备案 (ICP licensing)?
A: Not always. Requirements depend on the接入方式接入方式 (access method), node locations, and service model. Check with your provider.

Q4: Are China CDNs always more expensive than global CDNs?
A: Usually, yes—but the stability and speed gains are significant. Don’t choose on price alone.

Q5: Can I use a DDoS-protected CDN and a regular CDN together?
A: Absolutely. Many sites use a secured CDN for China traffic and a standard CDN for other regions.

Q6: Is CDN07 suitable for content-only sites?
A: Yes, but it’s especially strong for sites that need security and DDoS protection. Static-only sites may not need its full feature set.

Q7: Can a China CDN solve all slow-access issues?
A: No. Origin server performance and site architecture also matter—but a good CDN is the most critical piece.

Q8: Should a China CDN support all major Chinese ISPs (China Telecom, China Unicom, China Mobile)?
A: Yes. China’s multi-ISP landscape makes single-line CDNs perform inconsistently.

Q9: How can I test a China CDN’s real-world performance?
A: Run actual access tests from multiple regions and ISPs in China—don’t rely solely on official metrics.

Q10: When should I switch my China CDN provider?
A: When you see unstable latency, frequent attacks, or costs spiraling out of control—it’s time to reevaluate.
