Overseas CDN Acceleration for Chinese Websites: Optimizing Global User Access

If your website is ICP-licensed and hosted with a Chinese cloud provider, overseas users may experience significant latency issues. This is caused by limited international exit bandwidth and cross-border routing detours.

1. Problem Analysis

1.1 Causes of Slow Overseas Access

• International Exit Bottleneck: Limited total bandwidth from China to overseas
• Routing Detours: Traffic may pass through the US or Europe
• High Latency: China-US latency typically 200-300ms
• High Packet Loss: Packet loss can reach 5-10% during peak hours

1.2 Testing Methods

Use global node monitoring tools for testing:

# Test global latency with ping
ping -c 10 your-domain.com

# View routing path with mtr
mtr your-domain.com

Recommended Testing Tools:

• Checkly: 10+ global nodes
• Dotcom-Tools: 30+ global nodes
• Webmaster Tools: Domestic nodes testing overseas access

2. Acceleration Solution Comparison

2.1 Solution 1: Domestic CDN + Overseas CDN Dual Stack

Architecture:

Users → DNS Smart Resolution
       ├── Domestic Users → Alibaba Cloud/Tencent Cloud CDN
       └── Overseas Users → Cloudflare/CloudFront CDN

DNS Configuration:

yourdomain.com
├── A Record (CN) → Alibaba Cloud CDN CNAME
└── A Record (Global) → Cloudflare CDN CNAME

Recommended DNS Providers:

• Alibaba Cloud DNS (Accurate domestic resolution)
• DNSPod (Tencent Cloud)
• Cloudflare DNS (Global coverage)

2.2 Solution 2: Cloudflare China Network Optimization

Cloudflare partners with JD Cloud to operate China nodes, available for ICP-licensed use in China.

Configuration:

1. Enable China Network in Cloudflare (China Routing)
2. Submit ICP filing
3. Configure Enterprise plan

Note: Requires Enterprise plan, which is expensive.

2.3 Solution 3: Deploy Reverse Proxy Overseas

Deploy Nginx/Envoy as a reverse proxy overseas to cache static content.

Overseas Users → Overseas Proxy (Nginx) → Origin Server in China
                 └── Cache Static Assets

3. CDN Provider Overseas Node Performance

4. Best Practices

1. DNS Smart Routing: Domestic users use domestic CDN, overseas users use overseas CDN
2. Static Resource Separation: Host static assets for overseas users on overseas servers
3. Dynamic Request Acceleration: Use DCDN or overseas proxy to accelerate API requests
4. Testing and Validation: Conduct comprehensive testing with global nodes before launch
