Is it easier to achieve 99.999 with a single server cluster at one place 
(well, one L2 domain) or with the same number of servers spread out over 
the globe?

I guess that depends on whether your clients are all located in roughly 
the same place or not. I never stick all my important servers in the 
same L2 domain.
