My main site, no EMD, was hit at around the Same time with a 950 penalty. My best guess is that it is a duplicate penalty, link penalty and an over optimizing penalty. I have been trying to get out of it but so far nothing has helped so I am looking at anchor text, page duplication, thin content and so on... I have requested a reinclusion but they say I have no manual penalty so its got to be on page/on site penalty.
