I believe your first link is still version 20. Here is version 21: https://tools.ietf.org/html/draft-ietf-websec-key-pinning-21 .

Also, your second link point to a 404.

There is a 'g' missing in the link to Mozilla Wiki: https://wiki.mozilla.org/SecurityEngineering/Public_Key_Pinn... .

And https://tack.io doesn't respond for me whereas http://tack.io does.

Somehow I managed to break every single link. Fixed them now. Thanks for the heads-up!
