If you enable transfer acceleration and the accelerate endpoint is used to access your bucket, OSS charges transfer acceleration fees.

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 based on 1 GB for transfer acceleration and 1 GB for outbound traffic over the Internet. For more information about transfer acceleration, see Transfer acceleration.
