E.g., in a dump from April 2011 as well as in another one from January 2012, the article "Marseille" had the id 71486, while the article with the same name currently (according to the MediaWiki API as well as in the May 2014 dump) has the id 40888948. Does anybody have an idea how this might have happened and whether this is a frequent phenomenon?

AIUI, pages don't retain page id on delete+restore.

In this case Marseille seems to have had some surgery on 2013-10-25.
