To that end I'd be cautious of facilities in NJ. If you are dead-set on the US, Ashburn, or even better further inland such as Chicago or Dallas, may be better suitable if you do not plan on having redundancy in another facility. Frankfurt may be a better option solely on the basis that it is more "environmentally" stable (in terms of events that may disrupt the operation of the facility).
