You do realise that is a real dumb statement, don't you? :-)

A cluster of 10 machines, each on a different site. Guarantees from the 
power company - checked personally to see that aren't cheating - that 
you have genuinely independant feeds to these sites. Large UPSs, with 
diesel generator backups. Multiple diverse telecoms links between the 
sites, personally checked multiple times to see there is genuine 
diversity (Its a waste of time asking a telco for guarantees of this 
kind, as they lie by habit). This *might* start to approach 5 9's. Just 
having 10 servers means *very* little.
