An EC2 instance has an IAM instance role attached to it, providing it read and write access to the S3 bucket 'my_bucket'. You have tested the IAM instance role and both reads and writes are working. You then remove the IAM role from the EC2 instance and test both read and write again. Writes stopped working but Reads are still working. What is the likely cause of this behavior?
