I need to keep copies of all of the pages of a site (Fancyclopedia III). In order to do that I watch the site and use the watch e-mail messages to keep track of what needs to be downloaded to keep my copies up to date. Recently I began to suspect that the watch feature was not as reliable as I had hoped that it would be and I finally caught a failure that I could document. One page, "Dark Matter", was created and updated on 4/6, updated twice on 4/7, and the twice again on 7/7. I received watch messages for the first four actions but not for the last two.
