We haven't tried going to any ORG domains today, and we haven't had any support calls about this, but according to sources, it appears that ORG is having a bad hair day.
A couple of times in the past year, there have been attacks on root servers, but since it's only ORG right now, this might be a hardware or software problem, not an attack.
Oh, by the way, it's MAYDAY. In honor of pitcher and barkeep Sam "Mayday" Malone, I suppose we should all watch an episode of Cheers.
