Comcast User Help

OK, I need some help from Comcast users out there. I’m working on a site called http://www.guidebazaar.com and they switched over their DNS about a week ago and for some reason Comcast DNS servers do not seem to be picking up the change here in Fort Collins. If you users can see if the site comes up and let me know if it does or does not come up and which state you are in that would be greatly appreciated, you can PM if you don’t want to post here.

why not do an nslookup or netstat on the domain to see where the DNS server is from.

They are going through a proxy service, the who is records are showing the correct DNS server from both Comcast and from my work ISP which is not Comcast.

I did a DNS Lookup on your site and got back

Domain Type Class TTL Answer
guidebazaar.com. A IN 14400 69.65.111.11
guidebazaar.com. NS IN 86400 ns2.keepitsecure.net.
guidebazaar.com. NS IN 86400 ns1.keepitsecure.net.
ns2.keepitsecure.net. A IN 23692 69.65.126.246

Keepitsecure is the DNS domain they handle your name space. As you can see they have multiple servers which means they havent been able to update all of their servers yet which in turn COMCAST has not been able to update their servers either.

Here is COMCAST DNS Lookup:

Domain Type Class TTL Answer
comcast.com. A IN 300 69.48.228.103
comcast.com. NS IN 86400 ns1-auth.sprintlink.net.
comcast.com. NS IN 86400 ns2-auth.sprintlink.net.
comcast.com. NS IN 86400 ns3-auth.sprintlink.net.
ns1-auth.sprintlink.net. A IN 86400 206.228.179.10
ns2-auth.sprintlink.net. A IN 86400 144.228.254.10
ns3-auth.sprintlink.net. A IN 86400 144.228.255.10

Chances are they do not have your websites new DNS server in their list. If you notice COMCAST does not have a DNS server.

Thanks for the info, this will help me out. I have switched over many sites and have never had this type of problem.

I found out something else that may be the problem.

Read the Yellow and especially the RED report on your DNS. This may be the problem why you cannot reach the site. I dont think comcast is at fault. By the way I am not a COMCAST user.

That is a nice tool, thanks for the help. I like finding new tools like this, while I work on servers DNS is not my specialty.
