Read the following details carefully and modify your application configurations to ensure business continuity.

Details:

● For users who activate OSS after 00:00:00 (UTC+8) on March 20, 2025, the request to call data API operations using default public domain names (Example: bucketname.oss-cn-region.aliyuncs.com) for resources stored within buckets located in regions inside the Chinese mainland will be blocked. The error code "PublicEndpointForbidden", HTTP status code 400, and EC code 0048-00000401 will be returned.

● Users who have activated OSS before 00:00:00 (UTC+8) on March 20, 2025 are not affected.

● Internal domain names are not subject to this restriction.
