Updated the DNS record.
Since I have to reply now on this topic, I just wanted to say that I don't always immediately remember where bits of things are hosted, so when I first saw people reporting problems, I did have a mild panic attack and had to look up to find it wasn't on my server. hehe
Propagation theoretically can take 24-48 hours, although in more practical terms it tends to take more like 2-8 hours, so hopefully everyone will find this is working again soon.
