I am seeing objects named 2024-04-03-01-48-54-087C7DACE20DCF93 in my s3 bucket and am not sure why.

You probably have Amazon S3 server access logging enabled. If you're looking to disable it, you can follow this guide, which explains how to enable logging. Just do the opposite of what it suggests. You can find the guide here. If you wish to keep S3 server access logging enabled but need to change the destination, you can refer to this guide for instructions: link.

The objects named "2024-04-03-01-48-54-087C7DACE20DCF93" in your S3 bucket appear to be auto-generated filenames rather than your actual HTML pages. These filenames typically result from automatic processes or services that interact with your S3 bucket.

Here are a few possible reasons why these objects were created:

If you've configured CloudFront to log requests to your S3 bucket, these filenames could be CloudFront access logs. CloudFront access logs are generated automatically and provide detailed information about each request made to your CloudFront distribution.

If you're using other AWS services in conjunction with S3, such as AWS Lambda or AWS Glue, they might be generating these objects as part of their operations.

To better understand the origin of these objects and confirm whether they are CloudFront access logs, you can inspect the contents of these objects. If they contain log entries related to HTTP requests, it's likely that they are indeed CloudFront access logs.
