2. WebLuker:
Webluker is a one-stop operation and maintenance service platform. Although the entire technical team is relatively young, it has grown into the most well-known CDN service provider in China. In addition to free CDN services, it provides users with more stable, efficient and flexible services. The services include: providing advanced users with website CDN acceleration with greater traffic and load, domain name management, DNS resolution, intelligent resolution, cloud hosting, VPS, computer room management, server monitoring, website monitoring alarm and other functions. Free users can get 30 GB/month of traffic and 8 CDN Cache nodes, which is more than enough for personal websites. However, the biggest obstacle for many personal users is that the website needs to be registered.

3. DoCDN:
002The service that free users of DoCDN can get is the peak value of 128kb/s, the monthly traffic is 5G, and only one domain name can be bound. Compared with the 8 nodes provided by WebLuker, DoCDN only supports four nodes: Southern Telecom, China Unicom; Northern Telecom, and China Unicom. It may be because it has just started, so these advantages are not available to our users who use WebLuker. Since it is a domestic service, your website also needs to be registered.

2. Excellent free CDN services abroad
1. CloudFlare:
CloudFlareCloudFlare may be the earliest free CDN service that domestic netizens have come into contact with. If your website has users all over the world, then CloudFlare is definitely suitable for you. If your website program is WordPress, the official also provides an official plug-in for WP users, which can be set up in one go, and you can directly view the CDN traffic in the background. To use CloudFlare, you must use CloudFlare's DNS, and some of CloudFlare's IPs have been harmonized domestically. If your main visitors are domestic, it is not recommended that you use it.

2. SpeedyMirror:
SpeedyMirror Speedymirror is a free CDN acceleration service from the United States. Its servers are mainly distributed in the United Kingdom and the United States. It is more suitable for websites whose hosts are placed abroad. The disadvantage is that the network nodes are not as widely distributed as CloudFlare. Speedy Mirror can quickly create mirrors for your website in various locations. It supports static and dynamic pages, SSL, and anti-hotlinking functions. It is easy to use and does not require modifying the DNS server. Just set up CNAME alias resolution. Speedy Mirror only provides 50G of traffic to each free user, which is more than enough for personal sites.

3. Incapsula:
Incapsula is a free CDN in the United States, claiming to have a "global network". However, a simple test using just-ping and chinaz found that it only has four nodes: the United States, the United Kingdom, Singapore, and Israel. However, it seems that the European and American networks use anycast, which can be done with one IP, but this IP points to two networks, the US and the UK; the Asian part directly points to the Amazon EC2 network node in Singapore; as for the Israeli node, according to the results of just-ping, only Israel itself can access it, and other West Asian countries all use the UK node.

4. Yottaa:
YottaaYottaa uses the Amazon ec2 network. It is said that many node IPs have also been harmonized domestically, which is really cruel. Domestic users can only understand that the Singapore node of ec2 is responsible for East Asia, South Asia and Oceania, the US node is responsible for America, and the Irish node is responsible for Europe and West Asia.
