Hi, 

This is a message to maintainers of ROS mirrors. We have updated the infrastructure to support mirroring of the API documentation from a tarball download to an rsync invoction.  The new method takes significantly less bandwidth, processing, and diskspace to maintain the mirrors. 

The updated instructions have been posted on the wiki http://wiki.ros.org/Mirrors You will need to replace the download and unpack command with a single rsync command.  

Due to the improved performance for both the source and downstream mirrors I expect to switch the main wiki mirror over as well in the near future.  I will send a follow up message about that too. 

Tully
