* If the bucket endpoint has a `<subdomains>.<region>.amazonaws.com` format (or `<subdomains>.<region>.amazonaws.com.<suffix>` format for AWS China regions),
the Operator uses `<region>` as the S3 region name.
* If the bucket has a `<bucketname>.s3.amazonaws.com` [Legacy global endpoint](https://docs.aws.amazon.com/AmazonS3/latest/userguide/VirtualHosting.html#VirtualHostingBackwardsCompatibility) format, Mendix Operator 2.26.1 (or later versions) will detect the bucket region with a [HeadBucket call](https://docs.aws.amazon.com/AmazonS3/latest/API/API_HeadBucket.html#API_HeadBucket_ResponseSyntax).
In case the HeadBucket call fails, the Mendix Operator will use the default `us-east-1` region (only for bucket endpoints that match the `<bucketname>.s3.amazonaws.com` _Legacy global endpoint_ format).
* If the S3 bucket endpoint does not match this format, the Mendix Operator will use a default `us-east-1` region, as this works with most S3-compatible buckets like [Minio](#blob-minio) and [Google Cloud Storage](#blob-gcp-storage-bucket).

In some scenarios (legacy or custom S3 endpoints), this autodetection might not work correctly. In this case, you can manually specify the S3 bucket region by setting the [com.mendix.storage.s3.Region](/refguide/custom-settings/#commendixstorages3Region) Custom Runtime Setting. A manually specified `com.mendix.storage.s3.Region` will override the autodetected bucket region.
