Aliyun International Station has recently introduced a permanent free CDN package, which supports CNAME domain resolution. This free service is a significant advantage over Cloudflare's free version, as it allows for more flexible domain resolution. However, the free package has some limitations, including a limited number of nodes and no SLA guarantee. Users need to register an international account and bind an overseas credit card or PayPal to validate the service. The free package is only available for overseas users, which may result in higher latency for users in mainland China. Nevertheless, the service has received positive feedback from users, with many praising its high-speed performance and user-friendly interface. As the demand for cloud services continues to grow, Aliyun International Station's permanent free CDN package is an attractive option for businesses and individuals looking to improve their online presence.
