 BROADCAST_MESSAGE: >
-  We are close to hitting the 1000 bucket limit on AWS. | Before we work on a long-term solution,
-  please delete any unnecessary buckets and avoid creating more than you need.
-  Consider using sub-folders to manage different datasets instead of multiple buckets.
+  AWS have increased the S3 bucket limit from one thousand to one million. | While this means that the restriction on creating new buckets has been lifted, we still recommend that you use buckets efficiently.
