For information, I also had issues with the Voronoi SOP creating a suboptimal mesh output (disconnected points here and there) and found that the scale of the object can greatly influence the quality of the fracture. So just crank up the scale to reach a bounding box of around 100-1000 units (don't go too high or this might cause floating-point issues), apply the Voronoi SOP, and revert the scale back. Another helpful thing to do, as recommended by SESI, is to avoid an input geometry with non-planar faces by inserting a Divide SOP before the fracture.
Well, even with these 2 tips it still might not work depending on the input geometry.
