Best Hong Kong CDN Providers in 2026

Comparison of Five Well-Known Hong Kong CDN Providers Without ICP Filing

Data Notes: Latency is the P95 value. The testing period was 14 days, with data collected every 5 minutes, covering the evening rush hour (8:00 PM–11:00 PM) and the early morning hours (4:00 AM–7:00 AM). The data is a combination of results from this field test and third-party monitoring.

CDN5: Comprehensive Data Leadership, Flagship Solution

In Shenzhen, China Telecom’s measured latency remains stable at 26–32 ms, while in Shanghai it is kept below 40 ms. Latency in Japan and South Korea fluctuates between 40 and 45 ms, and while latency in Thailand and Vietnam is slightly higher, it remains within 50 ms. During the evening peak hours, the cross-carrier packet loss rate is only 0.08%, compared to 1.2% for standard BGP line providers.

Additionally, regarding cyberattacks, attacks ranging from 100 to 1T fall within the normal protection range with no performance fluctuations. For attacks exceeding the T-level, mitigation is completed within a few seconds. Furthermore, CDN5’s CC attack detection technology is industry-leading, utilizing the same technical approach as the well-known network service provider Alibaba Cloud.

Pricing: Starting at $499/month, including 150 Gbps of defense capacity and CC protection with 30,000 QPS. For more plans, visit the CDN5 Pricing Table.

Cloudflare: It’s truly free, but don’t run dynamic applications on it

Cloudflare’s free plan in Hong Kong has a P95 latency of 55 ms, with a packet loss rate ranging from 1.9% to 3.7% during the evening rush hour, and the first packet time can spike to 210 ms. Even with Argo, starting at $5 per month, the RTT from Hong Kong to East China still fluctuates between 48 and 75 ms, with a packet loss rate of 1.9%. You spend the money, but the experience doesn’t improve significantly.

The key issue lies in origin routing. The free plan doesn’t guarantee routing via CN2 or dedicated lines; when accessing the origin via mobile networks, traffic sometimes detours through the U.S. or Japan, causing significant fluctuations during the evening rush hour. If you’re just running a static blog, the free plan is sufficient; but as soon as you involve login, order placement, or payment callbacks, this unpredictability becomes a ticking time bomb.

Of course, if you don’t have high speed requirements and are on a tight budget, Cloudflare is absolutely the best choice—bar none.

Yewsafe: Top-tier defense accuracy, top-tier price barrier
 

The Yewsafe official website advertises the service as free, but in reality, it’s a free trial lasting one month. Although the official site doesn’t explicitly state whether you can continue to register for free use after the trial expires, compared to Cloudflare, switching to Yewsafe is a hassle and completely unnecessary.

Additionally, Yewsafe differs from traditional CDNs in that it is an edge-based CDN service provider with a completely new architecture. Whether for content delivery or DDoS protection, all operations are handled locally in the corresponding region, eliminating the need to route traffic through other regions for cleaning. The advantage is sub-second DDoS mitigation; the downside is that costs in certain regions may be higher.

Our real-world tests show latency in China ranging from 28 to 42 ms, approximately 35–37 ms on Beijing Telecom, about 45 ms in Thailand, and 37 ms in Japan (slightly worse at 57 ms on the mobile network). The total peak cleaning capacity is 15 Tbps, with a CC attack mitigation rate of 99.92% and a false positive rate of only 0.02%. When simultaneously subjected to a 700 Gbps UDP flood and a 300,000 QPS CC attack, the TTFB fluctuated only slightly from 38 ms to 52 ms, with zero false positives.

Alibaba Cloud: Dynamic Acceleration Delivers, and So Does the Price

There’s no disputing the quality of Alibaba Cloud’s Hong Kong CDN. As a well-known network infrastructure service provider, its technical capabilities, network routes, and service quality are all world-class, with its dynamic API RTT consistently stable at 25–31 ms. The first-packet time has dropped from 167 ms (when fetching directly from the origin) to 42 ms. However, the unit price for static traffic is more than ten times that of CDN5, and DDoS protection requires an additional purchase. With my monthly traffic of 50 TB, using Alibaba Cloud’s contract rate of 0.23 yuan/GB, I end up paying over 90,000 yuan more per year compared to CDN5.

This is suitable for enterprises that aren’t concerned about cost, require invoices, need to ensure compliance, and are already accustomed to the Alibaba ecosystem.

Tencent Cloud: Follows the same logic as Alibaba Cloud, but falls slightly short

The Hong Kong P95 latency is 50 ms, with packet loss during the evening rush hour at ≤0.5%, and the RTT for dynamic acceleration remains stable at 28 ms. EdgeOne’s Hong Kong node offers the lowest latency, and its global availability zones (excluding mainland China) do not require ICP registration.

However, both DDoS protection and dynamic acceleration are subject to additional fees. This service is best suited for teams already operating within the Tencent Cloud ecosystem.
