Appreciate the discussion here. You all may have just solved an occasional and annoying issue on my website. I'm a Dev at www.theblaze.com and we've had varied reports over the past little while that the site is inaccessible on Comcast. I use Comcast as well at home and I've noticed intermittent failures. My first thought was DNSSEC errors like those that took NASA down a few months back, but we don't use DNSSEC at all. Just checked, and our root record is indeed CNAME'd. One question though. Is there a single source to reference for the discussion I'm starting with our host?
