Within our site we have a number of areas where images, delivered from the CMS, are rendered on the pages.  Recently we have been seeing a lot of instances where the images are not showing when the page is viewed, instead we are receiving a 403 status against the images.  Eventually the image will resolve itself without any apparent intervention from our editors or admins.  The issue is only present in the production environment so debugging is incredibly difficult.

We are running EpiServer v11.9.2, hosted in DXC.
