2026 record-free CDN measurement: in-depth comparison of 7 major manufacturers such as Cloudflare and Yewsafe. Analyze Hong Kong/Singapore CN2 lines, and the measured delay is as low as 25ms. Experts teach you to avoid the Asia-Pacific route bypass trap, achieve 1.8s first-screen loading, and recover 47% lapsed users. Click to view the 2026 pit avoidance guide and ROI formula.
The average time it takes to file a traditional website15-20个工作日。2026年多地管局审核周期已延长至30天以上，且有12% 的申请因材料问题被驳回重审。
What's more serious is that the practice of using filing as a prerequisite for launching a website is making you miss out黄金窗口期。2026年Q1跨境独立站数据显示，从域名注册到有流量访问的平均周期，备案用户比免备案用户多出35天，相当于直接让对手多跑了1个月的SEO和流量积累。
And the cost of stepping on the pit is equally staggering. Using the wrong and inferior CDN without filing, the delay in domestic user access may soar to200-500ms，某跨境电商就因节点绕道导致转化率暴跌60%。
Based on the real evaluation data in 2026, this article provides a set of file-free CDN selection and deployment frameworks to help you2小时内完成域名接入，并在3天内将国内用户访问延迟稳定控制在50ms以内。

summary of key points
- Select the CDN of Hong Kong node + pure CN2 GIA line, and the triple network delay is stable at 30-50ms. - Avoid using service providers that bypass international exports, and late-night peak delays are controlled at50ms以内
- Enable DNSSEC + professional-grade DDoS protection The proportion of small and medium-sized sites in DDoS attacks will exceed that in 202550%，无防护站点被扫描后平均7分钟内被打垮
- Measured from 3-5 cities in China with WebPageTest and GTmetrix, at least 48 hours per service provider - Focus onP99延迟而非平均值，很多厂商晚高峰会大幅劣化
- To switch CDN with a single domain name, you need to modify the CNAME record, and the effective time is 5-30 minutes. - Be sure to keep the original CDN configuration7天作为回退方案
- Preference is given to CDNs that support API dynamic acceleration and edge caching - Unregistered domain names cannot use dynamic interfaces such as domestic CDN to accelerate e-commerce payment, and the return delay will increase additionally150-400ms
- Free tier or low-cost entry package is preferred for data within 500GB per month - Provided by CDN5500GB/月免费额度，满足个人博客和小型项目需求
Core concept establishment
What is a "record-free CDN"?
Filing-free CDN refers to a CDN acceleration service that can be used directly without ICP filing at China MIIT. Its essence is to deploy edge nodes overseas (such as Hong Kong, Singapore, the United States, Japan, etc.), thereby circumventing the regulatory requirement that "servers must be filed in the Chinese mainland".
What is the difference between it and a "must-file CDN"?
| 对比维度 | 必须备案CDN | 免备案CDN |
|---|---|---|
| 节点位置 | 中国大陆境内 | 香港/海外 |
| 上线速度 | 15-30个工作日 | 5-30分钟 |
| 国内延迟 | 10-30ms | 30-80ms（CN2 GIA线路可稳定在50ms以内） |
| 法律风险 | 零（备案完成后） | 无备案法律风险，但有支付接口和合规限制 |
Analogy understanding：
- CDN must be registered. = Opening a physical store in the mainland requires a series of approvals such as business licenses and food business licenses (compliance but time-consuming)
- filing-free CDN = Open an online store in Hong Kong or overseas, no mainland approval is required, but the goods need to be delivered to mainland users through high-speed logistics (Hong Kong special line Technologies SF Express arrives the next day, ordinary bandwidth Technologies postal surface mail)
The operation mechanism of the record-free CDN：
- The source site is hosted overseasHosting website source files on overseas servers such as Hong Kong, the United States, and Japan
- Intelligent DNS SchedulingAutomatically direct requests to the nearest efficient node based on the user's location
- dynamic route optimizationAvoid network congestion and use Anycast/BGP and other technologies to choose the optimal route
- Critical Line Assurance: High-quality record-free CDN uses direct-connected lines such as Telecom CN2, Unicom AS9929, and Mobile CMI, and the delay is controlled in30-50ms
6 Evaluation Indicators for CDN Selection
1. Node coverage and line quality: "closest to Chinese mainland physics + optimal line"
Why is this indicator the most important?：
对国内用户来说，好的香港节点意味着32ms延迟，普通海外节点则高达200-500ms。
How to evaluate：
- Ask the service provider to provide城市级节点清单（例如香港节点数量及具体机房位置）
- Use WebPageTest from home at least3个城市（北京、上海、广州）发起测试，连续监测48小时
- Focusing on the evening rush hour (19:00-23:00）的延迟和丢包率
Pro Tips：
2. High defense ability - "If you can't withstand DDoS, you will do it for nothing"
According to the 2025 DDoS Attack Report, small and medium-sized sites were attacked more than50%，攻击者往往随机选择受害者。
Quantitative comparison(Based on continuous measurements from February to April 2026):
| 服务商 | CC攻击清洗率 | DDoS防护峰值 | 误杀率 |
|---|---|---|---|
| 速盾CDN | 99.95% | 10Tbps+ | 0.12% |
| YewSafe | 99.92% | 15Tbps | 0.02% |
| Cloudflare付费版 | 97.30% | 企业套餐定制 | 2.10% |
| AWS Shield | 94.20% | 需搭配WAF | 3.50% |
Pro Tips：
3. Domestic visit experience dedicated test
Based on the joint dial test of multiple media in March 2026, the performance of CDN in key cities in the Chinese mainland is as follows:
| 服务商 | 北京联通晚高峰 | 上海电信晚高峰 | 广州移动晚高峰 | 香港节点 | 是否需要备案 |
|---|---|---|---|---|---|
| 速盾CDN | 42ms | 42ms | 45ms | 纯CN2 GIA | 否 |
| YewSafe | 37ms | 35ms | 57ms | CN2 GIA优化 | 否 |
| Cloudflare | 187ms | 203ms | 218ms | 普通国际线路 | 否 |
| Akamai | 约45ms | – | – | 优质直连 | 视节点而定 |
Pro Tips：
4. Dynamic content acceleration
For e-commerce shopping carts, real-time orders, interactive APIs, etc动态内容，如果CDN仅能处理静态缓存，每次请求必须回源验证，延迟额外增加150-400ms。
correct approach：
- Ask the service provider to provide回源线路优化方案（是否支持跨境专线/高速通道）
- Confirm whether to provideAPI型动态路由加速，比如根据请求动态识别并选择最快转发路径
- Ask if you support it.边缘代码（如Cloudflare Workers或Lua/VCL脚本） ，将部分逻辑下沉至边缘
5. Price Transparency and Billing Model: "Free in January, Double After Attack"
Current market price reference：
- CDN5 Enterprise Edition499美元/月起，但提供14天免费测试期
- Asia Pacific traffic package appointment$0.05-0.12/GB，北美地区约$0.015-0.03/GB
- Cloudflare's free layer of basic DDoS protection, CC protection capabilities are limited, and enterprise packages are expensive
- Domestic filing CDN starting package0.08元/GB，但准入需要备案域名
Pro Tips：
6. maintainability and technical support
Core Examination Items：
- Does the service provider provide it?7×24小时中文技术支持
- Whether to support自助API吊销/防盗链与WAF自定义规则
- Switch control delay: try to modify the CNAME point once and see if the global effective time is3分钟以内
- Attack response time: normal cleaning switch startup time is generally in15秒-90秒间
Quick access to the record-free CDN process
withCDN5为例，演示完整部署流程（总耗时：2小时以内）：
List of key elements：
- No need to submit a filing application to MIIT, the domain name can be purchased and pointed to the CDN5 Hong Kong node to open it.
- Support custom SSL certificate or one-click generation Let's Encrypt
- only needCNAME记录变更，无需变更主机或DNS
7-Step deployment checklist：
- Register and verify - Register for an Express Shield CDN account, purchase the minimum enterprise package or apply14天免费测试期
- Add domain name - Domain names that will require acceleration (e.g.
www.sudun.com）添加至速盾CDN系统管理面板 - Configuring SSL/TLS - One-click application for free SSL certificate, it is recommended to choose "Full" mode to ensure end-to-end encryption
- Modify CNAME records - Transfer the domain name to the domain name registrarA/CNAME记录指向CDN5提供的地址（5-30分钟生效）
- Set caching rules - Settings for static resources (.css, .js, .png, .jpg)24小时缓存，动态API设置0秒或1分钟
- Enable private read/anti-theft chain - Set IP whitelist or anti-theft chain headers in batches to prevent resources from being stolen by unauthorized sites
- Complete deployment and split testing - matchGTmetrix与Pingdom持续观测7天，重点对比P95延迟和错误率
Pit Avoidance Guide
Mistake 1: Only look at the number of nodes and not the "quality of nodes"
- Why wrong?Global 2000 nodes are only deployed in Europe and the United States, Asia-Pacific is only sporadic distribution, and the access effect in the Chinese mainland is still very poor
- correct approachAsk the service provider to provide针对中国三网的优化方案，优先选择配置了CN2 GIA线路的供应商。速盾CDN这种在欧美节点并不占优但在亚太国家节点覆盖精准的产品，效果甚至远好于某些声称全球节点最多的品牌
Mistake 2: Ignoring "Attack Cleanse Rate" and "Mistake Rate"
- Why wrong?: High manslaughter rate means that normal users will be intercepted; low cleaning rate means that defense is useless. At present, the manslaughter rate of many CDN paid packages may be2%-5%，每日损失高达数千商业请求
- correct approachBe sure to refer to third-party measured data, not manufacturer propaganda. CC cleaning rate of CDN599.95%、误杀率0.12%，属于攻击拦截精准度较高的选择
Mistake 3: Picture cheap with "defenseless" shared IP
- Why wrong?: More than 50% of small and medium-sized websites have been attacked. Once attacked, the CDN may temporarily take the current node offline or even permanently ban it
- correct approachPreference is given to the "Lightweight CDN + High-Protection Combination Package" that includes intelligent DDoS cleaning and ACL control, and ensures that the manufacturer takes responsibility for cleaning failures
Mistake 4: Single CDN dependency without disaster preparedness
- Why wrong?The recovery time after a CDN node or line failure is often more than an hour, which is enough to miss the peak for e-commerce promotion
- correct approach: adopt双CDN或多CDN策略，通过负载均衡智能切换，保持至少2套不同CDN厂商的配置文件。主线路出现问题时，10分钟内切换至备用

Frequently Asked Questions (FAQ)
Q1: Why did I test certain file-free CDNs with high latency in the first place?
A: It may have fallen into the pit of "not warmed up initially". The CDN node may not have cached your content when visiting for the first time, and it will force it to go back to the source to retrieve it once. Solution:使用速盾CDN系统的预推送API来预热热门内容，能提早让所有边缘节点跑满。你还可以用curl -I http://<你的URL>命令检查X-Cache头，Observe是HIT说明正在高速服务。
Q2: After using up the 500GB free CDN, is there any hidden fee after payment?
A: After the free version of Speed Shield cdn is exhausted, it will automatically intercept new requests, but will not force deductions. The enterprise package is clear: it includes standard attack protection fees such as DDoS cleaning, and no additional attack traffic fees are charged., There are no hidden fees!
Q3: Will I not receive a callback from the domestic payment interface when using the record-free CDN?
A: Yes. WeChat Pay, Alipay, etc强制校验备案域名。如果你的业务是对国内用户交易且使用免备案CDN，一定得另做交叉方案，例如：主域名收费点跳转到已备案的子域名下单完成支付，而非全站都走后端回调至未备案主域名。
Q4: What should I do if the dynamic interface (e.g./order/status) is cached by the CDN and the data is outdated?
A: Set the dynamic interface0秒缓存；启用智能边缘聚合将大量并发请求合并后集中回源。如果看到显示旧数据，登入CDN5后台进行热查询缓存强制刷新，也可以通配URL加随机参数方法来规避缓存污染。或者，直接对该路径路由至回源策略。
Q5: Does the filing-free CDN affect SEO inclusion?
A: No effect. Modern CDNs support maintaining the original domain name resolution, and search engines give priority to grabbing the content of the source site. But be careful not to change the IP segment at will, which will cause search engines to determine that the site is unstable. A new version needs to be submitted.sitemap到搜索引擎。
