Cross-domain Google Sitelinks

Google's sitelinks are the navigational links displayed below a main result; they're automatically picked by Google, and just show for some sites/ queries. Now it seems Google also shows other sub-domains among these links.... like uk.ask.com below www.ask.com in a search for ask (oddly enough, the subdomain link seems to use a different font, too). Does anyone know if this is new? [Update: Apparently not new then, except perhaps the font issue... thanks all!] [Thanks Russell!]
