webmaster tools identified two 404s

[sethladd]

http://api.dartlang.org/dom.html

and

http://api.dartlang.org/io/HttpServer.html

These should redirect to the correct location.

Also found this one in the wild:

http://api.dartlang.org/docs/releases/latest/dart_crypto/CryptoUtils.html

That should go here: http://www.dartdocs.org/documentation/crypto/0.9.0/index.html#crypto/crypto.CryptoUtils

And this link: https://api.dartlang.org/dart-core/List-class.html

redirects to /stable/index.html however it should probably return a 404 or at least redirect to /stable/dart-core/List-class.html
