Why do bookmarks stop working? The answer is simply that the information location pointed to by the URL in the bookmark has changed. The web is dynamic and changes over time with or without notice. Web sites are often updated with new information or new techniques to show the data better and faster. All of this has the potential to make saved bookmarks not work as expected for many reasons.
It's nice to be told changes are coming but in reality, bookmarks need continuous maintenance or updates as issues are detected or noticed. This problem is not unique to any particular web site.
Understand the the web content changes. When a web site address changes it effects not only bookmarks but also links from other pages. If done a random and without notice if requires catchup from many other web masters and broken links and searches resulting in 404 page not found. Why does the Aux keep changing address?
