I looked up this page on archive.org
It has copies for 4 months. march 2013-june 2013, archived when the page was gone. (so those archives from then are as good as saving a 404 error)
So for the last 6 months archive.org hasn't updated their copy of the page.
Is there any way to get archive.org to save the page as it is for the current date, because it has changed since they last saved it?
