The link is still on the Support Page at the bottom. I just called Tesla and they are aware of it but at this time do not know when it will be back up. They asked me to check back next week. To me it appears they are updating their web pages. Changes to "My Tesla" and "Autopilot" now have a different look to them. Autopilot now shows a video of a Model S going through the paces on autopilot and parallel parking.
