Re the 404 error: It seems as if you get served the old website unless you've previously navigated to the front page -- and any URLs which didn't exist on the old website gives you 404.
To verify, open [1] in Incognito mode -- you should get the old website. Open [2] in Incognito mode -- you should get 404. Open [3] in Incognito mode, then visit the previous links in the same session. You will get the new webiste.
Edit: It seems to split visitors on the cookie "enablev2=1", which is set on the front page.
