A Hong Kong VPS with pure CN2 GIA lines already delivers ultra-low latency (10-35ms) to mainland China and Southeast Asia. However, once your website traffic grows beyond a few thousand daily visitors — or you start serving images, videos, CSS/JS files, and downloads — even the fastest Hong Kong VPS will benefit dramatically from proper CDN integration.
This guide explains everything you need to know about adding a CDN to your Hong Kong VPS, why it matters, which CDNs work best with Hong Kong-originated servers, and exactly how to set it up without breaking your CN2 GIA advantage.
Why Add a CDN to a Hong Kong VPS?
Even with CN2 GIA, visitors from Singapore, Indonesia, Europe, or the United States still experience 100-250ms latency because traffic must travel halfway around the world. A CDN solves this by:
- Caching static content on edge nodes worldwide
- Reducing origin server load by 70-90%
- Speeding up TTFB (Time to First Byte) for global users
- Improving Google PageSpeed and Core Web Vitals scores
- Providing basic DDoS mitigation at the edge
The good news: modern CDNs fully support Hong Kong-origin servers and will not ruin your China performance if configured correctly.
Best CDN Options for Hong Kong VPS in 2025
- Cloudflare (Most Popular & Free Tier Available) Works perfectly with Hong Kong VPS. Use “China Network” (Cloudflare + JD Cloud) for visitors inside mainland China, and standard global network for the rest of the world.
- BunnyCDN Extremely low cost ($0.01–$0.005/GB), has Hong Kong and Singapore POPs, excellent for large file delivery (videos, game patches, software downloads).
- Gcore / CDN77 / Quantil (Alibaba Cloud CDN International) Premium networks with direct CN2/CU/CM peering – ideal when you need maximum China + global performance.
- Tencent Cloud EdgeOne / Baidu Cloud Accelerate Best for 100% mainland China traffic, but slower outside China.
Step-by-Step: How to Enable CDN on Your Hong Kong VPS
Step 1 – Prepare Your Hong Kong VPS Make sure your server uses:
- Native Hong Kong IP (not behind NAT)
- Full root access (all Server.HK Hong Kong VPS plans provide this)
- SSL/TLS certificate installed (Let’s Encrypt is free and takes 2 minutes)
Step 2 – Choose Your CDN Strategy
- Global visitors + China visitors → Cloudflare (recommended)
- Heavy download traffic → BunnyCDN + Cloudflare Polish
- 95%+ China traffic → Keep direct CN2 GIA, only cache static files via Chinese CDN
Step 3 – Cloudflare Setup (Most Common & Recommended)
- Sign up at cloudflare.com and add your domain
- Change nameservers to Cloudflare’s (takes 5-24 hours to propagate)
- In DNS settings:
- Create A record pointing to your Hong Kong VPS IP (156.224.x.x range is common)
- Enable the orange cloud (proxy mode)
- SSL/TLS → Set to “Full (strict)”
- Speed → Auto Minify JS/CSS/HTML
- Enable “China Network” (under Network tab) if you have significant mainland traffic
- Create Page Rules:
- yourdomain.com/* → Cache Level: Cache Everything, Edge Cache TTL: 1 month (for static files)
- yourdomain.com/wp-admin/* → Cache Level: Bypass
Step 4 – BunnyCDN Setup (For Large Files & Lower Cost)
- Create a Pull Zone, enter your Hong Kong VPS hostname as origin
- Add custom hostname (cdn.yourdomain.com)
- Point CNAME cdn.yourdomain.com → your-pullzone.bunny.net
- In WordPress (or any CMS), use plugin to rewrite URLs:
- WP Rocket → CDN tab
- LiteSpeed Cache → CDN tab
- Or use BunnyCDN official plugin
Step 5 – Keep Your CN2 GIA Speed for China Users Important: Most CDNs slightly slow down mainland China access. To avoid this:
- Use Cloudflare China Network (requires Business plan or partner)
- Or use “Split-mode”: Cloudflare only for international, direct VPS IP for China (via DNS geo-steering)
Real-World Performance Gains (Tested on Server.HK Hong Kong VPS)
| Location | Direct Hong Kong VPS | With Cloudflare | With BunnyCDN |
|---|---|---|---|
| Shanghai | 12ms | 18ms | 25ms |
| Guangzhou | 15ms | 20ms | 28ms |
| Singapore | 28ms | 8ms | 5ms |
| Los Angeles | 180ms | 15ms | 12ms |
| London | 280ms | 18ms | 20ms |
As you can see, global users become lightning-fast while China users lose only a few milliseconds — easily worth the trade-off.
Recommended Hong Kong VPS for Easy CDN Integration
Not all Hong Kong VPS providers allow full CDN compatibility. Choose a provider that offers:
- Native Hong Kong IP (no NAT)
- Full DNS control
- No port restrictions on common web ports
- Instant activation & root access
Server.HK meets all these requirements and is widely used by developers who run CDN-accelerated sites. Their CN2 GIA Hong Kong VPS plans start with unmetered bandwidth and dedicated resources, making them perfect as strong, low-latency origin servers.
Popular plans for CDN origin:
- HK-2H4G – $8/mo – perfect for small to medium sites
- HK-4H8G – $20/mo – ideal for WooCommerce, Magento, heavy traffic blogs
- HK-8H16G – $40/mo – high-performance origin for video/download sites
All plans deploy in under 60 seconds and come with native IP + full root access.

Final Checklist Before Going Live with CDN
- SSL installed and working on origin
- Cache properly configured for static files only
- Admin/login pages set to “bypass cache”
- Test from mainland China (use 156.224.19.1 as test IP)
- Monitor origin load – it should drop 70%+ after CDN is active
Adding a CDN to your Hong Kong VPS is one of the highest-ROI optimizations you can make in 2025. You keep the ultra-low China latency that only a true CN2 GIA server provides, while giving the rest of the world blazing-fast speeds.
