I’m experiencing this issue at the moment with, www.absolutejam.co.uk and absolutejam.co.uk, but blog.absolutejam.co.uk loads fine. Obviously this is still an issue because my URLs all point to absolutejam.co.uk, but the strange part is that all of the CSS etc. is loading using absolutejam.co.uk (eg. http://absolutejam.co.uk/css/main.css), but pages do not.
The first 2 domains had been associated with another repo previously, but not for a little while.
All domains are verified and have the same DNS configuration.
