Weird DNS issues for domains

I'm hoping someone on the list can help confirm that I'm not going
insane.
I have a customer with the domain 'mtrsd.k12.ma.us' The domain
should be handled by our DNS servers (dns-auth1.crocker.com & dns-
auth2.crocker.com)
The customer has an A record for www.mtrsd.k12.ma.us pointing to
their web server
The customer has subdomains for each school in the district which
have www records pointing to their web server via CNAME
Everything looks like it is configured properly on my servers but the
customer is reporting that certain parents (VerizonDSL, Comcast,
DirectWAY) can connect to certain website and not others. At this
point I think the problem is with the DNS servers at their ISP.
Can someone confirm my sanity? My zone of control starts at
mtrsd.k12.ma.us I do not have control over k12.ma.us
What do you all see for sanderson.mtrsd.k12.ma.us &
www.sanderson.mtrsd.k12.ma.us.
