Regions and Domains
Last updated: 2025-03-24 19:20:35
Overview
Tencent Cloud's Cloud Infinite (CI) supports multi-region storage, and different regions have different default access domain names. The region you initially selected for the bucket cannot be modified. You can select a region closest to your business location to speed up object upload and download.
Note:
After a bucket is created, the default domain will be generated. To view the URL, you can go to the CI console, click the name of the desired bucket, and click File Management > Details.
Regions and domains in the following table are COS domains. Old users can still use CI domains.
BucketName is the name you set for your bucket upon creation. To view its value, you can go to the CI console, click the name of the bucket, and choose the Bucket Configuration tab.APPID is one of the account identifiers assigned by the system after you successfully applied for the Tencent Cloud account. It can be viewed in Tencent Cloud console > Account Information.For domain names supported by legacy versions, see Legacy Domain Names.
