This might be somewhat of an abstract question but any lead or clue of some sort will be of help.
We have an app service on Azure running 2 instances and when we restart the Azure site then some of EPiServer content is not properly "published" for one of the instances.
What happens is that a few images are missing for most of the markets but only on one of the instances. The images that are missing are somewhat random and they do appear for some of the markets. When we republish the pages (master language) that contains the images then the images reappear for all markets. However restarting the site will, once again, cause images to disappear on one instance.
The EPiServer logs does not indicate that anything went wrong unfortunately. There's also nothing to see in the network traffic other than there isn't any call being made to fetch the missing images (which explains why they are missing on the site).
Do any of you have any lead as to why this might happen or have you had similar issues?
