OSS data centers are located in regions. Endpoints are the domain names that the other services can use to access OSS. This topic describes the mappings between regions and endpoints.

Regions and OSS endpoints for access over the classic network

Access over HTTPS is allowed in the classic network. The following table describes the public and internal endpoints of OSS in each region for access over the classic network.

Note
  • 1ECS instances can use internal endpoints to communicate with OSS only when the ECS instances and buckets are in the same region.
  • 2Transfer acceleration endpoints include global accelerate endpoints and accelerate endpoints outside mainland China. Accelerate endpoints take effect after transfer acceleration is enabled. For more information, see Transfer acceleration.
  • We recommend that you use third-level domains that are in the Bucket + Endpoint format to share links or bind custom domain names (CNAME). For example, the third-level domain for the oss-sample bucket in the China (Shanghai) region is oss-sample.oss-cn-shanghai.aliyuncs.com.
  • When you initialize endpoints for OSS SDKs, we recommend that you specify the parameter in the following format: http(s):// + Endpoint. For example, we recommend that you set the initialization parameter to http://oss-cn-shanghai.aliyuncs.com or https://oss-cn-shanghai.aliyuncs.com for the endpoint of the China (Shanghai) region, instead of the http://bucket.oss-cn-shanghai.aliyuncs.com third-level domain.
  • By default, the oss.aliyuncs.com endpoint maps to the public endpoint of the China (Hangzhou) region, and the oss-internal.aliyuncs.com endpoint maps to the internal endpoint of the China (Hangzhou) region.

Regions and OSS endpoints in VPCs

Access over HTTPS is allowed in VPCs. You can use the following endpoints to access OSS from an ECS instance in the same region.
Notice When you access OSS internal endpoints by using Cloud Enterprise Network (CEN), Express Connect, leased lines, or VPN, you must configure routes for network products. OSS divides internal VIP address ranges for each region into fixed address ranges. When you configure routes based on regions, you must configure complete four or six Class C IP address ranges as listed in the following table.
