Nope. That's more likely just the ups and downs of luck.
If there's a block/hour ratio of (more or less) 6 that means people still run their rigs but do not add new hardware (which had already been unfeasible before the last difficulty change).

So IMHO everybody is still on board (more or less) but right now it's not attractive to invest in new hardware. Should the price rise again we will see another rise in difficulty because more people will buy new hardware (new and old miners alike).
