I've seen some crazy stuff driven by the fear of broken links. One place I worked had all the traffic for their main landing page hitting a redirect on a subsystem because the subsystem had a url that was higher in google etc. I worked on the subsystem and rather then fix things in DNS and the search engines they preferred to expect us to keep our webservers up at all times to serve the redirect. We were on physical hardware in those days and while we had redundancy it was all in one location, made for some fun times.
