What about getting sponsored by Akamai ? :o)

One problem is that you can not monitor an application by just using 
logfiles. You want scripts to check your application servers works as 
intended, trigger warnings when performances are going lower than 
expected ... Nagios Ganglia is a first step, you might want more :o)

Having clusters in 3 differents places is no more different that 3 
clusters in the same room. You still have to manage 3 entities. I must 
agree it is usually easier to handle stuff at the same place (1 guy 
there, file transfers with 10Gb, easier to switch a server from a 
cluster to another).
