By disappear do you mean they are out of Google completely, or that they just don't rank?
They are out of Google completely. 2 sites are now showing in Google results. It happend in the last 3 hours.
I re-submitted the sitemap in Google Webmasters. Maybe this made Google take action...
Another new site that I made on March 29 is now showing more than 1000 visitors from Google for today. This domain is on the same webhosting account but is not affected.
Perhaps we are victims of the war between matt #*$! and Russian link building networks.
