BlobNotFound 404 error in error logs
Hi RichF,
Just a little piece of advice, maybe you should remove out the environment details from your logs before submitting.
I was able to take you prep environment details and access the site by simply adding the optimizely dxp domain to the end.
On to the problem, have you looked into your application insights? Insights should be able to tell you the severity of the issue and wether you need to address the problem.
If it is only a few say 10-15 that is managible, however if you are getting 500+ then you know there is something severaly wrong.
If you think this is severe, then I think you next approach would be to implement a global exception handler/middleware and only handle the 'Microsoft.WindowsAzure.Storage.StorageException' .
You could then use the nuget package AzureStorageExceptionParser, to log additional details.
Hopefully that helps with you investigation.

I see lots of the same errors in the logs on production and preproduction environment. I'm unable to determine the source but I believe the message contains identifiers I can use to determine the problem. Can someone tell me how to use these values to find the problem? I see no browser console errors when viewing pages.
I also see a rare server hangup response and wondering if the two are related.
