Hosted domain - how long for zone file updates?

[Klaas]

I have a domain hosted with Exetel. The only zone file entry I set up was a cname for www pointing to a hosted blog space.

An hour or so ago, as I have "moved" the blog to another server, I logged into my member facilities, and removed the www cname definition, replacing it with a A record for @, pointing to the IP address of the new host server. I thought that as the domain is hosted by Exetel's nameservers, the Exetel DNS servers would update pretty quickly.

However, it appears that the cname definition is still in force - pinging www.domainname.etc points to the "old" server, and pinging plain old domainname.etc says it is unresolved.

Any idea how long it will take to update?

Got up this morning, and it's all working, so I guess I was just a little impatient

I was going to guess "6-12 hours" but that was purely a guess based on non-Exetel based DNS updates so I didn't post it. Good that it is functioning now though
