you're confusing finite speed of light and relativity - they're not really the same (although they are of course related). the relativistic sense of "no correct ordering" is irrelevant to the problem that google are solving (two observers, watching google's machines, from different, high-speed spaceships, may still disagree about the order of what happens in paris and the usa, or even in two machines in the same datacentre, but google doesn't care). they've chosen gps time as a universal clock.
