This is happening to me frequently, and it only happens on DJF (the new one).
I'd click on a link, I would either end up with a blank page, or the page loads only until the breadcrumbs (forum -> misc -> site discussions) and after that it stays the dark grey colour of the background.
I use the latest version of Chrome, haven't tried it in other browsers yet. But I would say right now out of every 5 clicks, one is like that.
