The following changes have been implemented in today's update:

1. Users can select either "km" or "miles" in their user settings.
2. Summary system statistics are now displayed, so users have an indicator of whether the site is backed up.
3. Processing jobs for existing cities is now prioritized over indexing new cities.

Note that there is currently a large backlog due to an influx of new users.  Most of the backlog is due to the site indexing new cities.
