Your site's speed depends 99% on choosing the right network route.

After years of running websites, I've realized one thing: the biggest factor affecting access speed from mainland China isn't "whether there's a CDN in Hong Kong," but what network route your Hong Kong CDN uses.

Many think a CDN is just about "being in Hong Kong." But when you run real applications, you'll face issues like:

• Your site becomes as slow as a slideshow (like PPT) at 8 PM.
• High latency spikes persist even with DDoS protection.
• Massive variance in cross-border latency (50ms vs. 300ms) from the same location.

Why such a huge performance gap for CDNs in the same region?

The answer: CN2, BGP, and Anycast are fundamentally three different network architectures.

Let's start with the basics.

1. What is CN2? Why Do Webmasters Love It?

If you serve users in mainland China with any cross-border traffic, CN2 is almost unavoidable.

CN2 (ChinaNet Next Carrying Network) is China Telecom's premium international network. Simply put, it offers:

• Direct Cross-Border Routes (No detours)
• Lowest Latency
• Most Stable During Peak Hours
• Lowest Packet Loss
• Highest Price

Especially CN2 GIA (Global Internet Access), the top-tier VIP route within CN2.

Why do webmasters prefer it?

Because most online services (websites, e-commerce, APIs, live streaming, SaaS) rely on one critical metric: the speed for mainland users accessing Hong Kong.

Slow cross-border = slow page loads for users.

Peak hour instability = lost orders/transactions.

High packet loss = API failures, blank admin panels.

CN2's advantage: These issues almost never happen.

That's why many Hong Kong DDoS-protected CDNs and data centers standardize on CN2—it's reliable.

But CN2 has clear drawbacks:

• It's expensive.
• Bandwidth is limited (depends on the provider).
• Node coverage isn't as broad as Anycast.

If you're on a tight budget or your service isn't latency-sensitive, CN2 might not be the best choice.

CN2 in a nutshell:

If your primary audience is in mainland China, CN2 is the most stable cross-border route you can buy—period.

2. What is BGP? Why Do Many Cheap CDNs Use It?

BGP (Border Gateway Protocol) is the global internet routing protocol. In Hong Kong data centers, you'll commonly find:

• Hong Kong Multi-Carrier BGP
• International BGP
• Hybrid Local ISP Networks

What's a BGP CDN?

Simply put:

A Hong Kong data center combines lines from multiple local carriers (HKIX, PCCW, HKT, etc.) using BGP and offers CDN acceleration through this blended network.

Compared to CN2, its characteristics are:

Advantages:

• Cheap (40%–70% cheaper than CN2)
• Fast for local Hong Kong access
• Stable for overseas access (due to multi-carrier blending)
• Many CDN nodes started with BGP (Cloudflare, QUIC.cloud, etc.)

Disadvantages:

• Not necessarily fast back to mainland China
• Can be unstable during evening peak hours
• Highly variable cross-border latency (anywhere from 50ms to 300ms)
• Not suitable for sensitive services, APIs, or cross-border e-commerce

Many webmasters get burned by focusing on "low cost" while ignoring the mainland-to-Hong Kong cross-border bottleneck.

BGP in a nutshell:

BGP is suitable for content sites, image galleries, news sites, and tool websites, but not for services requiring high-performance access from mainland China.

3. What is Anycast? Why Does It Seem So Unpredictable?

If CN2 is a "dedicated line" and BGP is "multi-line," then Anycast is:

"Globally distributed nodes broadcasting the same IP, with users automatically connecting to the nearest one."

Cloudflare, AWS Global Accelerator, and Google Cloud CDN use Anycast.

Its biggest advantages:

• Extremely fast for global users (connects to nearest node)
• Highly resilient and stable
• Single IP covers the globe (no DNS changes needed)
• Inherently strong against DDoS (traffic is dispersed globally)
• Preferred for gaming, video, APIs, and SaaS

So why is Anycast often considered unstable for China access?

Because when accessing from mainland China, the cross-border exit point isn't fixed. Sometimes it uses CN2, sometimes regular ISP lines, sometimes routes via Japan or Singapore. Any detour increases latency.

Anycast in a nutshell:

Anycast is incredibly strong for overseas users. For mainland users, it's "unstable but sometimes very fast," depending heavily on the provider's capabilities.

4. Where Exactly Do Hong Kong's Three Main Routes Differ?

(Cross-border TTFB + Evening Peak Stability + Packet Loss)

Let's get to what webmasters care about most—real-world performance differences.

Instead of just theory, here's data from a year of monitoring three typical routes from Beijing, Shanghai, and Guangzhou to Hong Kong.

① Cross-Border TTFB (Time to First Byte) Comparison

Why such a big difference?

Whether the cross-border route is direct is the decisive factor for website speed.

② Evening Peak Packet Loss Rate

Packet loss is devastating for APIs, image streams, and WebSockets. The more sensitive your service, the less suitable BGP becomes.

③ Evening Peak Latency Jitter

5. Is Anycast Good for China Access? 90% of Webmasters Get This Wrong.

If 80% of your users are in mainland China: → Anycast is NOT the best choice.

Reasons:

1. Anycast "contests" for China exit points—sometimes using good routes, sometimes poor ones.
2. Routing behavior across China's three major ISPs (China Mobile, Unicom, Telecom) isn't uniform.
3. No fixed cross-border path.
4. Access speed depends heavily on the provider's BGP optimization and node coverage.

But if over 40% of your users are overseas: → Anycast is the most robust architecture.

Its strength: One-time acceleration setup works globally—no need to pick nodes country by country.

6. How to Choose for Common Use Cases?

① E-commerce / Finance / Payments / SaaS Backends → CN2 (or CN2 + DDoS Protection)

Every lag spike can cost you money, especially for payment gateways which must be rock-solid.

Recommendations:

• CN2 + DDoS Protection
• CN2 GIA
• CN2 Optimized

Ideal for: E-commerce, ERP systems, internal APIs, critical interfaces.

② Content / Image / Download Sites → BGP (Cost-Effective)

If your site is read-heavy, high-concurrency, and can tolerate higher latency from China:

→ BGP is sufficient. Performs very well for image galleries and news sites.

③ SaaS / Tools / App APIs → Anycast First

Your users are spread globally?

→ Anycast is the most stable choice, perfect for multi-country APIs.

④ Mixed Traffic (China + Overseas) → CN2 + Anycast Hybrid Architecture

Many premium CDNs (including CDN07) now support:

• China traffic routed via CN2
• Overseas traffic routed via Anycast

This is the "best bang for your buck" solution.

7. Webmaster Pitfalls Summary: Choosing the Route is More Important Than Choosing the CDN

• Hong Kong location ≠ Fast speed
• Relying only on Ping values is wrong
• The evening peak tells the real story
• BGP: sometimes fast, sometimes sluggish
• Anycast unpredictability → depends on provider quality
• CN2 is expensive but the most stable
• Beyond the route, DDoS protection capability also determines experience

9. Understanding Routes is Key to a Truly Fast Website

There are many Hong Kong nodes and even more CDN providers.

But the real difference-maker isn't "how many nodes," but whether you choose the right route.

• Don't understand routes → rely on luck forever.
• Understand routes → operate smoothly and profit reliably.
