After the customer updated to RHOSO 18.0.15, he noticed quite critical issue - which has been already found and fixed by upstream [1].

Glance is not expecting ‘/‘ character in SK for S3 bucket and it's trying to rewrite the image url. The customer has a ‘/‘ in their SK - so all the images from S3 stopped working and glance started to rewrite their url, corrupting the entries in database.

This is critical for all customers who use S3 backend.
