Flex 2 LiveDocs are still up and running (your first link worked for me, too). However, if you are using Flex 2.0.1, you should use the docs under http://livedocs.adobe.com/flex/201/
But you're right in that Google isn't catching the 2.0.1 Language Reference stuff. I'll look into it. Thanks for the catch, Randy Nielsen Flex Documentation Manager Adobe Systems Incorporated
