I have had similar problem with my named. I was searching reason of this
behaviour of my named. I have put one option to my named.
It is forwarders option.

        forward only;
        forwarders {156.17.5.2;};

You can add forward only this only forward queries to your comcast 
caching dns servers.

In forwarders put one or more ip addresses of your comcast caching
servers.

The reaseon of this is that named try to contact to authorative servers.
And it can take some time to get respond from them.
but if you put forwardes you will be using closer dns so the queries
will be faster.

Form more reference read bind manual.
