404: Page not found, upgrade info. 1.5:: codex.wordpress???

Hi, does anyone know when the upgrade and installation pages for 1.5 are going to be back up? I was wanting to look at Canadian version of the upgrade notes by NuclearMoose—- just because, eh. like hoser…. ha he he.

The link I want:
http://codex.wordpress.org/Upgrading_WordPress

I get this page instead:
http://wordpress.org/Upgrading_WordPress

The link has being down for the day so far and I was hoping to have a look at them to do a upgrade today. Or, if the page has moved, could someone get me the new link? Please…. =)
