Post at will wesley, anything that could remotely help is welcome!
I'm baffled by this problem and I now have it as well, whereas previously things were fine on my computer.
I know it's intermittent, mostly happening on the homepage. I checked apache logs and it happens on other urls too, but very rarely. As I see it in the logs with apache returning 404's, it also has nothing to do with caching or proxies whatsoever, something I thought was causing this when I first saw it.
I am really sorry for the trouble and hope people will find their way back to f1t after getting the infamous blank page now for a day or two even.
