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

Regions and OSS endpoints in the public cloud

The following table describes the public endpoints and internal endpoints of OSS in each region in the public cloud.

  • : The internal endpoint can be used by other Alibaba Cloud services within the same region as OSS to access OSS.
  • For more information about the usage and the composition rules of OSS domain names, see OSS domain names.
  • By default, oss.aliyuncs.com maps to the public endpoint of the China (Hangzhou) region, and oss-internal.aliyuncs.com maps to the internal endpoint of the China (Hangzhou) region.
  • For regions marked with an asterisk * in this topic, the name of a region may be different from that of the region on the OSS Pricing or OSS Resource Plans website. However, they both represent the same region. For example, the US (Silicon Valley) region is the same as US-West-1 or US-West. For more information, visit OSS Pricing or OSS Resource Plans.
  • You can use a dual-stack endpoint to access your bucket from your client that supports IPv4 or IPv6. For more information, see Use an endpoint that supports IPv6 to access OSS.

Acceleration endpoints

If transfer acceleration is enabled for a bucket, the following acceleration endpoints are available:

  • Global accelerate endpoint: oss-accelerate.aliyuncs.com. Transfer acceleration access points are distributed across the world. You can use this endpoint to accelerate data transfer for buckets in all regions.
  • Accelerate endpoint of regions outside mainland China: oss-accelerate-overseas.aliyuncs.com. Transfer acceleration access points are distributed across regions outside mainland China. You can use these accelerate endpoints to map a custom domain name without an ICP filing to a bucket in the China (Hong Kong) region or a region outside mainland China.

For more information, see Transfer acceleration.
