Where to report broken links on Unity's website?

I've been anxiously awaiting the latest Unity patch release (4.5.5p1) and just saw that it has been released. The problem? The Mac download link links to a file that doesn't exist: http://beta.unity3d.com/download/4234258080/unity_update-4.5.5p1.dmg

I'm not sure if this should be reported as a bug, posted here, in feedback, etc. Any guidance would be greatly appreciated as I need this patch ASAP.

Thanks!
