Over what distance can quantum entanglement remain instantaneous?

We know that once quantum particles become entangled, one reacts instantaneously when the other is disturbed. How far apart can this apparent Faster Than Light (FTL) reaction stretch. Do large masses obeying mass attraction exhibit the same level of entanglement, or does gravity stay below the speed limit© of the universe? If any FTL effect is possible, how does this not violate the Causal Ordering Postulate—the Universal Spped COP?
