I have checked my logs and nothing is showing at all for the time that it happened. Nothing out of the ordinary in any of the vBulletin logs.
I disabled all the plugins via the config file, then enabled just the essential few. That cured the problem of not getting access for non-logged in people.
So the mystery as to why all users were banned. It looks like an attack on my site, but not sure how as of yet.
