what

• All load balancer types will be able to log to the s3 bucket.

why

• The missing policy info prevents logging from all load balancer types and is incomplete according to AWS documentation.

references

• closes #9 which is technically not the actual issue which says server side encryption is preventing the logging capability.
• See the various bucket policies in the following links:
