So if the Web server implements the HTTP protocol properly, it should never send an 304 status code back to us. This response is not what we expect, so we actively report it as an error even though it does not necessarily mean that the Web site is down.

I don't know where you got that from but it is totally totally wrong.
A 304 status code means that the requested resource has NOT BEEN MODIFIED it is a response to the If-Modified-Since request header that is sent by caching user agents.
This is the response code that stops browsers downloading resources that have not been changed since the UA last requested it eg:
javascript files, images, stylesheets and static html pages.
