The download link to get a repo as a zip file is boken on custom domains.
For example, this link used to work and now produces a 404: http://hg.berniecode.com/animator/get/tip.zip
The download page for that repo - http://hg.berniecode.com/animator/downloads - still advertises the broken URL.
The non-custom domain link works fine: https://bitbucket.org/berniecode/animator/get/tip.zip
I've marked this critical because it has basically disabled every software download link I've ever distributed.
