A couple of updates. First, downloading the normal package from eclipse.org I've found that the 503 error is not there. I've also noticed that the find and update software menus and screens are different than the ones the ubuntu install provides. Since it works, I really wonder if the packaging is all the problem is here.
Second, there is a related bug going back to 11/2009.
