As of this posting, ftp.drupal.org has been down for about five hours. This is kind of a bummer, because as long as FTP is down, you can't download new modules.

Or so I thought. If you use Drush, you can easily check out the code for the latest stable release of a module from Git using the --package-handler argument:

drush dl betterselect --package-handler=git_drupalorg

As always, Drush figures out which version of the module (or theme) is the latest and grabs that for you.
