Nameserver propagation - over a week to fully complete?

[jdbnd]

I changed nameservers for one of my sites over a week ago, and the old server is still getting some traffic (only a tiny trickle - the vast majority of traffic is going to the new server).

Does anybody know if there's any standard for how long it will take for the change to propagate COMPLETELY (100.00%), or are there just a few ISPs out there that suck? ; )

Thanks,

Joe

Over a week is a long time these days, but more than some ISPs just suck. Don't know of a standard. Somebody else probably will. When I get stuck with moving a site, I usually calendar a month as a nice round number that is more than enough. Then I burn down the old server, delete everything, and make a full clean break to the new server/host.

theoretically it should depend on the REFRESH parameter value in your SOA record but at worst case it should be based on the value of your EXPIRE parameter.

If you work with a big and serious hosting company and ISP, the DNS will be updated every 15/30 minutes.

Given that not every ISP are equal, could be a good practice let the old sites in place for two or three days or even a week with any kind of link or redirection to the new site's IP.

When advising somebody who is complaining that the domain that they purchased 2 minutes ago isn't visible is that it can take "up to" 3 days.

My UK based ISP seems to pick up new .uk names within the hour, usually quicker.

check the authoritative DNS record..

Dumb question... where would I find the authoritative record? The nameservers are on a VPS I am hosting, and the techs there tell me everything is in order with them... if I use dns lookup tools, I get the proper (new) IP address. But I still get a trickle of search and referral traffic to the old server.

The domain is registered at [a registrar] and that's where I changed the DNS records.
