Hello, is it possible to svn up the /home/wporg/public_html/ directory on all sandboxes?

There was a change in coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. to WP_Site which got reverted later. A sandbox which still has the old WP_Site will pollute the cache with a broken object which ends in a site_id = 0 entry in the database and making the site inaccessible.
