Same thing happened to 2 of my review sites! One of them is more of an affiliate site, but it is technologically much more sophisticated than 99% of other review sites out there.
I wish G would consider THAT in their quality scores, but they aren't sophisticated enough.
My main site got clobbered by both Panda and Penguin, but these past two days have totally killed it.
