Retirement: Azure CDN – Migrate to Azure Front Door on December 1, 2025

Azure CDN which is currently provided in Microsoft Azure operated by 21Vianet (“Azure China”) will be retired on December 1, 2025\. This change affects all customers currently using Azure CDN in China. Azure CDN is built on top of local CDN providers’ POPs with API integrations. Due to this architecture, Azure CDN lacks native and deep integration with the Azure platform. As demand grows for more integrated and developer-friendly solutions with built-in security features such as Web Application Firewall and Private Link to origins, we are introducing Azure Front Door as a native CDN service in Azure China and retiring the Azure CDN service. Migrate to Azure Front Door or an alternative CDN provider before November 15, 2025\. After validation successfully, please delete the CDN resources before November 15, 2025\. If you don’t migrate by November 15, 2025, Azure Front Door team will migrate eligible Azure CDN profiles to Azure Front Door. However, if your Azure CDN profile is disabled or has no active request in the past 3 months, or your Azure CDN profile isn’t compatible for migration based on the gap mentioned in [Azure CDN and Front Door comparison](https://docs.azure.cn/frontdoor/azure-china-cdn-and-afd-comparison), Azure Front Door can’t and won’t migrate your profile and your service will experience disruption from December 1, 2025\. In this case, please migrate to an alternative CDN solution before November 15, 2025\.
