Comcast DNSSEC

Hadn't seen this mentioned yet. http://blog.comcast.com/2012/01/comcast-completes-dnssec-deployment.html Comcast has signed all their managed domains, as well as deployed DNSSEC resolvers for their customers. And they're encouraging others to make the jump to DNSSEC now as well, especially e-comm/banking sites. Nice work guys, any of the Comcast guys on the list want to give us an idea how much work is involved in this from a large-scale service provider perspective to do it? Any big caveats you encountered that people should watch out for? Jeremy "TheBrez" Bresley brez@brezworks.com
