For All Those Hit Hard From June 6th-June 10th

After seeing all the threads posted its no coincidence that many people have been hit hard in the last few days. Basically the point of this thread is to gather info from the people who were hit and see if we can figure out whats going on.

My Facts:

- I have 15 websites
- Only one of my websites was hit. It was my top earning website and has basically been completely knocked out. I had over 200 page one rankings from 20 pages of unique content.
- It was in an information and education niche with some high search counts
- I had 20 pages of unique content and about 40 pages of syndicated articles from article ranks.
- I had done very aggressive link building for this website for about 3 months hitting with xrumer, scrapebox, pretty much everything under the sun. I had mellowed out the last 2 months, just using article ranks, BMR and some se-nuke but no Xrumer, blog comments for a few months.
- All of my other websites have seen the same treatment and are still fine. They are "thinner" sites though just 2-3 pages but all had syndicated articles on them as well. Some sites had only 2 pages of totally unique content and 100 pages of syndicated articles and are still ranking well.
- Sometimes at about midnight my site will show up in the serps for about 10 minutes and then poof gone again. I also get a few drips of traffic from my major keywords which means that some servers still have my site ranking somewhere in the US. Mind you this is very minimal compared to what I was getting. For a search term that would normally get 100 views a day I am getting maybe 3-4, but they are coming from the exact search term.

My Penalty:

- Site lost all its rankings and my major pages where links were built can only be found deep into the 500-900's and not for their normal search terms. They rank but for search terms they weren't optimized for.
- The only pages I have that break the top 500 are the pages that didn't see much link building.
- The pages that are ranking in the 500-800's just seem to be ranking for the wrong search terms which strikes my as odd.

My Thoughts:

Is this panda 2.2?
I don't think so personally. The penalty is too stiff for too many sites. Ive heard so many sites having very similar stories and it just seems way too harsh of a penalty. Its not like I went from #3 to number #87. I went from #3 to nowhere to be found for almost all terms. I also don't think the timetable for Panda 2.2 has come yet from what Matt Cutts has said.

What happened?
Is Google possibly cleaning up servers, transferring things or just doing major shuffles? Thats I guess what my hope is. The fact that this was my only site affected and that so many other people have had issues last week lends me to believe this could just be a Google glitch of sorts. But then again it may be a penalty.

I for one can suck up this loss. I can let it ride out for a month see if things change. The site earned well but I have others doing well and it wasn't making so much that I can't live with moving on. I just don't like not knowing what happened at all. It seems so arbitrary. I would love to hear the specifics and thoughts from other people in a similar boat.
