Yesterday, Google's search web snapshot was 17, how is it going back to half a month?
A few days ago, I saw a Free Book at TSS, but when I logged in; I saw a few news and books didn't exist! After clearing the browser history and cookies, those content have not appeared; they will see those content when they visit again next day!
Strange, why?
It is not a dozen hours, and there should be something for more than a dozen hours.
