About a year after Blogger introduced custom domain publishing , they segmented the custom domain publishing process. In order to avoid database corruption, which was a frequent cause of the "Another blog ..." problem , they introduced a delay period, which we call "Transition" . Transition lets them delay key blog updates - until the world wide DNS infrastructure has a chance to reliably update with information about any new Google custom domains. In the beginning, Transition lasted almost exactly 72 hours, and delayed creation of the "301 Moved Permanently" redirect from the BlogSpot to domain URL. Later, when Following became a fixture on most blogs, we observed that the Followers gadget was also being updated on a Transition based delay.
