[AusNOG] Am I being unreasonable.... MelbourneIT

Wed Sep 3 11:15:55 EST 2014

My view would be delegation time + standard TTL (86400) + fudge factor (a few hours extra) = time to remove.

If they have a system that currently removes them, it wouldn’t be too hard to simply have that system use a time based calculation like this before it actually does the work.

Imagine if the second you had a port request for a phone number, the losing carrier just started rejecting all calls to that number until the port was complete and it wasn’t their number any more.

That is in essence what they are doing with your DNS zone, though obviously simplified….

So let me play devils advocate here, what would you like them to do ?

The way I see it they (Melb IT) have two options:

1. You delegate the hosting to other NS, they drop the zone from their NS (which is what has been said below, how it happens NOW)
2. They keep the zone active on their NS while you set it up at another provider and then at some later point in time you/they have to remove it from their NS

I think we'd all agree that it's pointless (and bad form) to have zones kicking around on your NS that are not delegated to that NS. It's untidy and worse case is it will produce false replies for anyone that happens to try and lookup something from that zone from the 'old' NS.

So if they were to go with the 2nd option they run the risk that this will happen, old/stale zones that are no longer delegated to Melb IT NS, but still exist on them. The only way to avoid these stale zones would be to either:

i). Rely on customer to delete them (or create a ticket to say migration was complete and they can now be deleted).
ii). Have some sort of script that runs on a daily/weekly basis and compares zones delegated to zones that exist on NS and delete any zones that are no longer delegated to Melb IT NS.

We all know that relying on customers to do anything is fraught with problems. If you want it done, you need to do it yourself. Also remember that a good proportion of Melb IT customers may not be so DNS literate.

If they scripted it, you just increase your work load, have potential for problem and still potentially have people who would complain because the script ran at 2300 Friday and they had started the redelegation process at 2200 Friday (ie. 1 hour before script start) and so they still wanted the domain to stay on the old NS for another few days (of course you could mitigate against this by checking each day and flagging stuff as "to be deleted" then leaving it for a few more days before it actually gets deleted, but really how far do you take this !)

It's a bit of a hard line, but I can see where they are coming from. It hopefully produces the most consistent result for all at the end of the day and saves them wasting resources. You're no longer wishing to use their NS, why should the zone continue to exist on their NS ?

At least now that you know about it, you can factor it into your migration process.

regards,
Tony.

Yikes thats harsh.

See if you can set your TTL's down real low for the important records
(A, MX etc) wait a day or 2 then do it - at least hopefully then the
world is aware of low TTL and the time from them removing from their
NS's to servers checking your new ones should be quick.
