This is tangential, but isn't http://www.root-servers.org/ still the authoritative source for DNS. I was browsing DNS options (switched to open-DNS) but the main http://www.root-servers.org/ site is down. It appears to be cached as recently as this month with a map, but is not responsive. A few other "detector" sites have it down. Is this important, or does it not show up because it is a resolver?
