TIL works for me :shrug:.
Yeah. Me too. My bad. Good point.
I only tried the IP Address before, without actually checking the URL. I am getting slack in my old age...
Now I'll have to wrack the brain cells as to why this is so.
Edit: Virtual web-sites at that address? That's the best I can come up with at the moment, but doesn't explain why some people can't access the URL.
