If you enable transfer acceleration and use an accelerate endpoint to access your bucket, Object Storage Service (OSS) charges transfer acceleration fees.

Note This topic describes only the definition of transfer acceleration fees and the billing methods of transfer acceleration. For more information about the detailed price, see OSS pricing page.

Transfer acceleration fees are calculated separately and based on the outbound traffic over the Internet. For example, an accelerate endpoint is used to download 1 GB of data from a bucket that has transfer acceleration enabled. OSS charges fees for transfer acceleration and outbound traffic of the data over the Internet. For more information about transfer acceleration, see Transfer acceleration.
