I still think "Ulysses" would be the most apt name,

Or maybe Sisyphus - who was condemned to roll a stone to the top of a hill only to watch it roll down to the bottom, where he had to start all over again ;)

I think reseller has the right take here. This is more like an infrastructure change. As far as I can remember, we've never seen these rapid oscillations in ranking on the same IP address. I also can;t believe that Google would settle for such instability over the long term.
