I can assure you that if folks could not resolve cnn.com and dslreports.com that there would have been several open threads on this forum and ours and I would have been involved in that issue.
I would agree but considering I couldn't resolve dslreports.com I couldn't post at that point and since I had my own fix to the situation I considered it resolved.
I really don't feel like wasting more hours than needed troubleshooting issues for Comcast.
