Problems with SHAW ISP DNS server

I am having a problem with a domain name that I recently moved hosting for. The domain in questions is and is registered with Two weeks ago I moved the hosting from midphase to a hostgator VPS with my own custom DNS. Which are and  I updated the names servers at and the  site transition went smooth and everything seemed to be working however a few days later the site stopped working for my client. (but not for me) I think I have narrowed the problem down to their IPS's DNS servers which are run by shaw. They run DNS servers at and

If you do an NSLOOKUP and then enter
the enter
set type=SOA
then enter

the following is returned

Primary name server =

It seems as though shaw DNS servers are refusing to update and even worse they seem to be flopping back and forth between the new and old nameservers.

A call to the shaw tech support said that the SOA was set incorrectly but follow ups with domainsatcost hostgator and the old host midphase seem a say everything is set correctly.

Is it possible that there is a problem with shaws DNS servers how can I indicate this to them or is there in fact something set wrong which I may be missing.

I know DNS servers take a while to update but this has been over 2 weeks now

I was able to temporarily fix the problem by asking the old host to make a redirect from their dns to my new hosting IP which is

I would like to cancel the account with the old host though and insure that this is running properly.

Can anyone provide insite into the issue?

I performed a nslookup for and it returned the IP
I confimed that the domain name whois records point to:

Used nslookup to point to Shaw (assuming the correct dns server)
> server
Default Server:

Served by:







So all indications are that the dns tranfer went good and you are correct that their ISP has issues
Suggest calling Shaw and have them perform some nslookups to confirm problem.
