maxmoritz, I also think this update is about external linking, more precisely sitewide linking.
Well I kind of hope you're right, because then it would be relatively easy to fix. However, I think there's more to it than that.
To be more concise: From what I'm seeing this update seems to be about links and it seems to affect entire sites.
