Whether this is a set of long, [three mile] cracks, or a multitude of much smaller ones isn't obvious to me. My hunch is therefore: one big one, followed by lots and lots of ongoing smaller ones.

My response is: We have three shelters. Those are the ones we should be using.

A novel is balanced between a few true impressions and the multitude of false ones that make up most of what we call life.

To avoid surprises later, spend enough time to know people initially. Don't just ask the obvious. Go the extra mile... Be creative and unconventional...

We end up with a group of large predator vortices preying on smaller ones, which in turn prey on smaller ones still, forming a food chain of vortices.

What makes it a problem, regardless of why, is that smaller companies are the ones who have fewer defenses in place. There are no large dedicated IT staffs in place, or large budgets for technology, so it's a double whammy.
