Xtra DNS continuing to resolve names after DNS moved away

Friend has bought a business, including a domain name, it was hosted with xtra,
now has being moved to another host within nz, but xtra are still resolving
internally on there DNS rather then getting the records from the correct name
servers.

How long will it take there shitty dns to realise that its not authoritive and
drop the records? They are in essence impersonating someone elses authority by
providing DNS to there clients when they are not authoritive.

 

How long has this been going?

If longer than 24 hours, log it with their helpdesk - they're usually
pretty good at resolving these sort of issues.

 

whats the TTL for the dns server?
I usually make mine 24 hours, but you should check Xtras dns record with
dig (or possibly nslookup)

 

Probably never. My wifes business was in the same boat a while back after
transferring away from Xtra and closing her account. You'll have to
contact Xtra to get them to remove the zones.

It was only months later that she figured out that she wasn't getting any
email from Xtra users, and complained to Xtra that the issue got resolved.

She eventually got the mail (Xtra had kept her mailboxes open too, despite
the account being closed - so these customers didn't get a bounce either),
but a lot of business and goodwill went begging as people assumed she was
ignoring them.

Yep - agreed.

 

Yes - you often need to contact them to sort it out. I've always found
them to be pretty helpful and responsive and the easiest way to sort it
out is to email them. The address is soa at xtra dot co dot nz.
