Sorry I could have been clearer. The archive.org page that shows all scans[1] will mark dates as orange (4xx), green (3xx), or blue (presumably 2xx). The reason I don't think that the link you posted is indicative of something is that all the scans of that url resulted in 4xx's. As opposed to scans of index.php[2] which primarly show 2xx responses. Any framework, Coldfusion or not, will generally throw a 404 when you hit paths that don't exist.
