My domain registrar (GoDaddy) says it *may* take 48-72 hours for the

I found that changes are seen very quickly in my laptop (no proxy), but
Are you running a caching DNS server on your laptop? I have also seen
changes propagate within a few minutes to my own intranet caching DNS
server.
take a long time to penetrate squid in the office.
Assuming that you have done things correctly on your DNS tables:
The point is - DNS records from your SOA server are pulled by other
DNS servers and cached. Besides setting the TTL values etc, your SOA
DNS server has no control over the other DNS servers; which is the
point made by Raja.
Your proxy server is probably caching the DNS entries as well. As a
test, make a change in your DNS then stop/start your proxy server.
See if the change is picked up the Proxy server.
