Azure Platform(File Server Upgrade) causing my web app to restart

Over last few days I have noticed that my webapp automatically restarts. I used the Diagnonstics and Solve Errors blade to see what is the cause of the problem.

Then under the webapp restarted section I see that my app restarted due to Platform(File Server Upgrade) and the description is On Instance RD281978FA5321, your application was recycled due to a file server upgrade.

Is this something Microsoft doing or am the cause of this somehow? thank you for your thoughts.

The deployment of your app uses the file system. When you create an app service, the underlying file system is mounted to a storage volume.

Using Local Cache can help mitigate when the underlying volume is undergoing maintenance because your app will copy the /site and /siteextensions contents to the VM instance upon start up. Once copied, the VM will point to it's "personal copy" of contents. Check out https://learn.microsoft.com/en-us/azure/app-service/overview-local-cache for more information.

See thread for more details.
