What does it MEAN!?!? *argh*  (please read the following, first)

Myself and a friend of mine have been trying to figure out WHAT THE HECK has 
gone wrong with my record.  We got it working fine early April, two weeks 
later DNS stopped pointing for my domain.   I simply saved and re-sent the 
record, and it worked for another couple of weeks, and then got lost April 
28th or so.  This time I cannot get it to take at all....   I also had my ISP 
(PacBell)  make sure that they performed reverse delegation yesterday, so 
that GraniteCanyon could run my zone.

Here's a copy of my record
