It may just be that the admin has closed the thread. What thread is it you are talking about? If you are talking about the CPP down thread, then chances are that they just closed it to prevent flamewars or trolling or something in the thread.
The thread looks kinda screwed up, possibly because every page is so goddamn long. Try to refresh bypassing your browser's cache (Ctrl+Shift+R in Firefox). Eventually you get the button.
