S3 bucket not accessible after wrong policy added by Admin

Question

Hi,
i have Administrator access and full s3 access as well.

I was updating S3 bucket policy and i think i wrongly did deny to all.

After that even i have all the admin access , i am not able to access the particular S3 and hence not able to reconfigure the bucket policy.

This seems like a bug in AWS , please clarify the same.

Answer

It sounds like you have added a Deny rule on a Bucket Policy, which is overriding your Admin permissions. (Yes, it is possible to block access even for Administrators!)

In such a situation:
Log on as the "root" login (the one using an email address)
Delete the Bucket Policy
Fortunately, the account's "root" user always has full permissions. This is also why it should be used infrequently and access should be well-protected (eg using Multi-Factor Authentication).

You can also open a support case and they can assist you further on the same.
