Glad to hear that it works for you, Jon. This is quite an embarrassment... it seems like all of a sudden all updated browsers interpreted 301 redirect codes in a new way (in the correct way in fact) by permanently caching the redirect. That's bad of course since our update page was by no means meant to be permanent...
