Pages that disappear just for a period

I often try and get my head round what actually happens to those pages that dissapear for days to week s at a time and then come back stable. Im not talking about the constant appear/re-appear observation. My case rlates to totally stable pages that suddenly dissapear for days to weeks then come back totally stable. Often related to just minor changes but often no changes at all. Where the flux pf some pages can easily be nailed to them sitting on a moving threshold, the case im relating is quite different. Its almost as though there is a totally separate index for dubious pages. Pages seem to move from the main index to what i call the scrubbing index where they seem to undergo forensic inspection. If true why would a seperate index be needed? In my musings i hypothesise that in this separate index google does some sort of relationship analysing between the whole dataset. In some way i wonder if they need to seperate good and bad pages to create a clinical environment in which the deep scrubbing/cleansing can take place. Just my thoughts. WSithout google id need to get a real life!

I suspect that certain kinds of changes on sites without a strong trust factor already in place result in a new trust check-up from Google. That would explain what you are seeing.

but i would expect that to happen on the fly, not requiring removal. You are addressing what may trip the disappearance while i am wondering what happens after removal and why this cant happen while the url remains in place. Pages can go missing for weeks before returning to total stability. This doesn't fit with a trust check, whatever that may be.

Whatever Google is specifically doing when they temporarily remove urls that recently changed content, they aren't sharing the details. I'm sure the temporary disappearance has to do with many factors, including the mammoth size of the data set and all of the metrics for it that they store. "On the fly" trust checking may be more challenging than anyone without comparable data set experience can conceive of.

But the fact is that they are doing it - and the exact "why" of it is in their internal knowledge, and not likely to be shared with the public.
