I just transferred my last three domains (including this one) from GoDaddy and when I did, I failed to notice a DNS issue. I just thought it was taking a while for the dust to settle. So 24 hours later, I finally decided that something was buggered up and... what do you know? It was.
But it was easily fixed and a minute later, we're back! I'm sorry you had to do without the site all day (all 3 of you).
