Subject: Mirror status improvements
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix sorting issues. '', 'unknown', and '∞' should now always sort after
  anything else in the list.
* Add a completion percentage column; this will tell you at a glance if a
  mirror is sometimes unresponsive. This should probably be incorporated
  into the mirror score.
* Make a few more things dynamic in the template, like the time back the
  page reflects.
* Add some additional template tags for formatting things.
