I'm sure all the effort Google put into being able to compile google3 for Power resulted in significant price concessions from Intel, which I imagine was the point of the project in the first place.
Original was just "google". There was also "google5" but not 4.
What's google3?
It refers to all of Googles code. And in this case the possibility to run it on PowerPC servers.
Sorry for the jargon. google3 is the name of their perforce repository that contains all of their backend code, everything that runs in their datacenters.
