AT&T / Verizon DNS Flush?

[stevenbriggs at gmail.com (Steven Briggs)]

Yeah...I know.  Unfortunately, the domain was "mishandled" by our
registrar, who imposed their own TTLs on our zone, THEN turned it back over
to us with a 48HR TTL.  Which is very bad.

I really appreciate all of your help, guys!
