I've just tried doing a WP install with SSH using subversion:
svn co http://core.svn.wordpress.org/tags/3.2.1 .
and on two separate servers it comes back with the following error
svn: PROPFIND of '/tags/3.2.1': could not connect to server (http://core.svn.wordpress.org)
Is there currently an issue with the WordPress Subversion Repository?
