 I was hoping to have an upgrade for Download.osgeo by the next release of
 the LiveDVD(August), looks like the current issues with the Blades has
 made this a more urgent matter. Below are some notes on ideas we might
 want to implement in the replacement service.

  1. Finish ticket:336 - Antivirus scan new uploads (unclear if it was
 finished)
  1. For non-SAC members with access use rssh to limit accounts to SFTP
 only. This can be used to prevent shell access, port forwarding and all
 sorts of other ways hacker might try use a compromised account.
  1. Consider implementing a mirroring system, with something like
 http://www.mirrorbrain.org/ or https://fedorahosted.org/mirrormanager/
   * These applications keep an eye on the mirrors and can be configured so
 md5 etc are hosted on the main site but files can be selective mirrored on
 other servers. They also scan for status and verify that files match the
 main mirror.
   * The url to download is still the same, the manager automatically
 routes the download with a redirect to geographically closer mirrors, less
 impacted mirrors, etc.
   * Mirrors do not have to be complete mirrors they can be partial, and
 TOS rules can limit bandwidth on mirrors with limitations.
   * simgislab has offered a mirror(Ukraine), I may be able to offer a
 mirror (US-West) and a mirror in Asia and Australia(Lisasoft?) would
 immensely increase international download speeds.
   * This may also solve ticket:515 as it will route requests to multiple
 mirrors
  1. A Newer OS than the current is needed, something that allows for
 larger than 2 GB file downloads(Possible Apache issue). Consider XFS
 filesystem or EXT4 for increased speed.

 Please add additional ideas to the ticket so we can discuss them when we
 discuss the resolution of the current Blade hosted services.
