Leo: That presumes the people at the bottom care about the big picture. I'd hazard to guess that the people who participate in this listserv *do* care, but if Dilbert has even any correlation to real life, then just as often there are people who build DNS/DHCP/etc redundantly because that's what they were told to do, but don't have the initiative or weren't directed to look at the bigger picture. At the end of the day it depends on these grunts' managers to be sure that things are being designed and implemented properly. And even then, we know how personalities, resources, and internal inertia more of than not develop and grow networks that aren't BCP-friendly.

I am amazed how many times inside of an ISP the folks deploying the DNS and mail servers are firewalled from the folks deploying the network, to the point where you have to get to the President to reach common management. This leads to them making choices in opposite directions that end up costing extra money the company, and often resulting in a much lower uptimes than expected. Having the network group deploy a single point of failure to the "Tier 4" data center the server guys required is, well, silly. <snip>
