DNS Resolving issues. So for related just to Cox. But could be larger.

For all it's worth, it might be Cox ignoring TTLs and enforcing their 
own update times instead.

Wait 24-48 hours, and it should probably fix it all up.

I'm not seeing anything majorly broken with your system except the SOA 
EXPIRE being ridiculously large.
