I've gone through the Confluence wiki and updated all the pages containing hg urls to point to the new repository locations.
Unfortunately the new SF project infrastructure doesn't support commit-hooks yet (although they are working on it: https://sourceforge.net/p/allura/tickets/2809/). So we lost the commit email until that ticket is resolved (looks like soon...) and we re-configure it.
The IBM regression machine (piano) is pulling from the new hg URLs.
I think ANU machines are still pulling from the old mirror (hopefully fixed soon) and we need to tweak the cattrack configuration to fix the URL for commits in the emails (also to be fixed soon...)
