This question already has an answer here:
If I'm not mistaken, last two seasons of Star Trek The Next Generation were aired in parallel with first two seasons of Star Trek Deep Space Nice, and most of the episodes in both series had their stardates matched. Are there any remarks to issues mentioned in ST:TNG "Force of Nature" (possible destruction of space fabrics by using warp drives) ever addressed or at least mentioned in Star Trek Deep Space Nine?
From what I saw so far (just starting DS9 season IV) there is no such thing. We have a strict declaration in "Force of Nature", that under no circumstances, except for an extremely dangerous situations, no Federation ship can speed more than warp 5. Yet, we have many clear examples in DS9 in season II and III, where we can see Defiant speeding at warp 8 or so in situations, which barely can be taken as extremely dangerous.
Is there any in-universe explanation for this "glitch"? Or is there something, that I don't follow and there is nothing to explain here, as there is no "glitch"?
