RRS (http://recipes.yoctoproject.org) currently redirects to http://recipes.yoctoproject.org/rrs/recipes/2.4/M4/ None of the recipes on that page have upstream information (upstream version field is empty).
Now the data seems to have re-appeared. It was broken for a while (since last week I think) so maybe worth investigating -- I think in the last 30 days RRS has been usable and up-to-date for less than a week.
Due to bitbake client/server changes now the meta path is not included when tinfoil is loaded. Anibal implemented the fix that brought back upstream info. It can be seen at http://git.yoctoproject.org/cgit/cgit.cgi/layerindex-web/commit/?h=rrs&id=feab3b1a858c739d9b0007b5d8ed7f489a92acd2
