Apart for the forum (temporarially) the rest of the site should be serving CSS/JS from our static domains (static.scirra.net to static4.scirra.net). This should improve page performance (it looks like on the homepage in my initial tests it's speed up for as much as 100-200ms).
It required another DNS propogation which I left for a few days, I've also run some propogation worldwide checks and they all came back clear, but if you have any issues please post them in here.
