Are S3 buckets region specific?

When we go to S3 in AWS console in "Global" option it shows

"S3 does not require region selection."

But when we create new bucket there it asks for Region !

So are S3 buckets region specific ?

The user interface shows all your buckets, in all regions. But buckets exist in a specific region and you need to specify that region when you create a bucket.

If you don't specify a Region when you create a bucket, Amazon S3 creates the bucket in the US East (N. Virginia) Region. Therefore, if you want to create a bucket in a specific Region, you must specify the Region when you create the bucket. Buckets created after September 30, 2020, will support only virtual hosted-style requests.

S3 buckets are region specific, you can check to get the list of end-points based on the region

From the doc on creating S3 bucket

Amazon S3 creates bucket in a region you specify. You can choose any AWS region that is geographically close to you to optimize latency, minimize costs, or address regulatory requirements. For example, if you reside in Europe, you might find it advantageous to create buckets in the EU (Ireland) or EU (Frankfurt) regions. For a list of AWS Amazon S3 regions, go to Regions and Endpoints in the AWS General Reference.

Also from UI, if you look at the properties for each of your bucket, you will see the original region

Yes, S3 buckets are region specific & while creating a bucket one need to specify the target region for the respective bucket answered Jul 11, 2018 by Mrunal • 680 points 0 votes

Yes S3 buckets are region specific.

When you create a new bucket you need to select the target region for that bucket.

For example:

Hope it helps.

Yes S3 buckets are region specific. When you create a new bucket you need to select the target region for that bucket.

How it works now is that if you are expecting the content to load fast globally, you create a bucket for every region you want your data to load quickly from, but use 'Versioning' to auto duplicate content from one bucket to the other.

Click on one of your buckets, then go to Management, then go to 'Replication'. Follow the instructions to setup a rule that will copy from one bucket to another.

Congratualtion, you now have globally fast content from a single bucket.

I appreciate if this seems a little off-piste, but I think this is what we are all really looking to achieve.

Amazon S3 Website Endpoints When you configure your bucket as a website, the website is available using the following Region-specific website endpoints. Note that the website endpoints are different than the REST API endpoints listed in the preceding table.

Bucket Regions When you create an S3 bucket, the bucket is created in a specific region. Knowing the region that your bucket is in is essential for a variety of use cases such as transferring files across buckets located in different regions and making requests that require Signature Version 4 signing.

If you have a large number of buckets, you can filter them by region using the region parameter. Get-S3Bucket -Region us-west-2. You'll notice below I only have buckets in the U.S. West-2 region, and, therefore, all of my buckets are still displayed in this example: PS>Get-S3Bucket -Region us-west-2 CreationDate BucketName

By following the guidance in this post, you can restrict S3 bucket access to a specific IAM role or user in your local account and cross account, even if the user has an Admin policy or a policy with s3:*. There are many applications of this logic and the requirements may differ across use cases.
