Last Friday I changed the title description and contents completely on a page preparing for reindexing near the end of the month. This page has a very good position for one of my keyword. To my surprise Sunday this new page showed up. Intermittently it reverts to the old page.
Currently the old is showing. When the old is showing on www, www2 and 3 has the new page . But when the new shows up on www it is the same on 2 & 3. I have seen this shift 3 time. Is this common for google to shift like this? Hope this make sense.
