CNAME domain name | A CNAME domain name is a system-generated, independent resolution endpoint used specifically for binding custom domain names. When you need to bind your own domain name, such as img.example.com, to a bucket, you point it to the system-assigned CNAME domain name instead of the generic default bucket domain name. The CNAME domain name is used only for DNS resolution of custom domain names and cannot be used for direct access requests. | 2025-12-22 | All | |
Preventing file overwriting | If you want to prevent objects in an OSS bucket from being accidentally or maliciously modified after the initial upload, you can set a rule to prevent overwrites for the bucket.

Resource pools support priority-based throttling | When multiple business systems share the same OSS resource pool, the priority-based throttling feature allows administrators to set 3 to 10 priority levels for different business objects, such as buckets, bucket groups, or requesters. You can configure a separate minimum bandwidth commitment for each level. When bandwidth is limited, core services, such as online transactions, are prioritized. Low-priority services, such as log backups, use the remaining resources. This ensures that important services are not affected by traffic bursts from other services and enables differentiated Quality of Service (QoS) management within the resource pool. | 2025-09-23 | China (Qingdao), China (Hangzhou), China (Hong Kong), US (Silicon Valley), US (Virginia), Japan (Tokyo), South Korea (Seoul), Singapore, Indonesia (Jakarta), Philippines (Manila), Thailand (Bangkok), Germany (Frankfurt), UK (London), UAE (Dubai) | |

Server-side encryption | OSS supports server-side encryption for uploaded data. When you upload data, OSS encrypts the received user data and then persists the encrypted data. When you download data, OSS automatically decrypts the saved encrypted data and returns the original data to the user, and declares in the returned HTTP request header that the data has been encrypted on the server side. | 2012-11-04 | China (Hangzhou), China (Shanghai), China (Qingdao), China (Beijing), China (Zhangjiakou), China (Hohhot), China (Ulanqab), China (Shenzhen), China (Heyuan), China (Guangzhou), China (Chengdu), China (Hong Kong), US (Silicon Valley), US (Virginia), Japan (Tokyo), South Korea (Seoul), Singapore, Malaysia (Kuala Lumpur), Indonesia (Jakarta), Philippines (Manila), Thailand (Bangkok), Germany (Frankfurt), UK (London), UAE (Dubai) |
