Was anyone hit by BOTH the 'Phantom' update as well as Penguin 2.0?

I'm interested to know if Phantom was just a "pre-Penguin" 2.0 or if it was a completely different update. Thoughts?

So, I've probably dug into "Phantom" as much as anyone, and I'm afraid the picture isn't very clear. I've heard of people who got hit by Phantom and then recovered at Penguin 2.0, people who got hit and then hit again, and I've seen multiple situations where people got hit by Phantom only.

My gut feeling so far is that this was an independent update and not a Penguin 2.0 test. They might both be related to link factors or seem conceptually similar, but I don't think Phantom was an early or partial release. It happened across data centers and appears to follow a pretty typical algo change pattern.
