How can I determine the region for a public AWS S3 bucket?

I know I can determine the region for AWS S3 buckets I own by doing:

aws s3api get-bucket-location --bucket <my-bucket>

but how can I determine the region for a public access bucket (which clearly I do not own)?

If I try to access one of the AWS Open Data buckets like noaa-goes16:

$ aws s3api get-bucket-location --bucket noaa-goes16

I get:

An error occurred (AccessDenied) when calling the GetBucketLocation operation: Access Denied
Solution

  • Yeah, you would think this would be easier to figure out, but here's the method I use:

    $ curl -sI https://noaa-goes16.s3.amazonaws.com | grep bucket-region

    which returns:

    x-amz-bucket-region: us-east-1
