I see domains dropping again from #1 to nirvana for no reason since 4 days. Even on really small-you-need-only-4-links-to-get-to-the-top-keywords for sites that have been there for years or for keywords like the company-name. I can only explain that by the usual data-chaos G might get during every update. Hope this whole roller coaster will stop soon.
