When creating a bucket, you can specify a region for the bucket based on your requirements on the response latency, price, and request source. The specified region cannot be changed after the bucket is created.

OBS is available in multiple regions. However, functions available on OBS may vary in these regions. The actual graphical user interface (GUI) prevails.

After a bucket is created, all objects uploaded to the bucket will be stored in the data center of the region.
