Exactly 24 hours ago two of our sites dropped 80% in visitors coming from Gooogle while the rest of our sites just waved up and down about 5%

It is the same behaviour that we noticed on 10th of September of 2009, and previously on August of the same year. We recovered 1 month later in both cases, but with a tremendous impact in our incoming.

It looks like a Google's hiccup, not something we have done 'bad', but we are suffering the consequences (quite badly). A little info from Google would be much appreciated, at least to know what is the name of the sickness that is killing us....
