However this will need manual intervention as the mirrors are not setup to self reconfigure the cron jobs. As such assuming you're running the standard configuration you can just run the following commands.
sudo puppet apply ros_mirror.pp --modulepath=/etc/puppet/modules:/usr/share/puppet/modules:.
And you should see an output like:
Warning: The use of 'import' is deprecated at /home/ubuntu/mirror/ros_mirror.pp:3. See http://links.puppetlabs.com/puppet-import-deprecation (at /var/lib/gems/1.9.1/gems/puppet-3.8.7/lib/puppet/parser/parser_support.rb:110:in `import')

If you have manually configured the cron jobs. Please update them accordingly.
We will keep the old rsync end points on through at least the end of this week. But since the wiki has become quite unstable we do not want to take a very long time to make this transition.
