As so often happens, I forgot to note what my client picked up for a return address. This is the first of several items that I meant to send to the list. My apologies to Mr Greco. On 6/13/2010 14:17, Larry Sheldon wrote:

It's always been a BCP good idea to have your DNS have secondaries in another non-fate-sharing AS, even though everybody from Microsoft on down seems to feel the need to rediscover this.
How about if the source database (not the relevant zone file, but the collection of data on some computer from which a zone file is created.
How about [...] is /what/? Unavailable? The zone files are still in place. Not really a problem in the overall scheme of things; I realize that some people have engineered things so that this will be a problem, but that's a choice.
Yeah, it is a choice to keep the source data in a database (think DHCP system or something) WHERE IT MAKES OPERATIONAL SENSE TO SO.
What happens if that source data can no longer be transferred to the master zone file located on the DNS server placed somewhere else WHERE IT MAKES OPERATIONAL SENSE TO SO, and the network is severed between them?
How about the case where the master zone file has be amputated and the secondaries can no longer get updates?
I'm not sure what "amputated" means here, but considering the case where the master itself is amputated, and the secondaries can no longer update, generally speaking, you log into the secondaries and twiddle their configs to make them masters. This requires some planning, preparedness, and procedures, but is in no way a crisis, unless you've failed to do the planning, have failed to prepare, and haven't followed your procedures.
Amputated = severed = cut off = disconnected = no longer able to communicate with not to be communicated with.
Did not see that that was going to be so hard to understand.
Should have known better, I guess.
How that works in the case where a government mandates something specific happens within your zone file is of course debatable, but possibly more back towards the original topic.
Uhhhhh....actually that WAS the original topic.
