Late Friday night, Google began rolling out Penguin 3.0.
Google's John Mueller said in a video hangout minutes ago that the roll out is now complete and fully done. So the rankings should stick around Penguin until they run another Penguin refresh.
John Mueller said 46 minutes and 35 seconds in that as far as he knows it has rolled out completely. But he wouldn't add if more signals were updated in the algorithm or if it was just a refresh.
I've been trying really hard to get more details from Google around this Penguin 3.0 update and will continue to bring you facts from Google and the industry around Penguin.
Forum discussion at Google+.
Update: John Mueller updated me on Google+ saying, "I might have spoken a bit early, hah - it looks like things may still be happening. I'll double-check in the morning."
