I'm seeing a few sites return today that have been awol for a week or so, including the one i mentioned here:
They have come back with the majority of keywords producing a slightly lower listing (up to 4 positions lower). I would say the common feature of these sites is that they have got slightly ropey back link profiles, in terms of being biased towards blogs and forums. I don't mean just blog comments, mainly links in blog posts.
