It should be at least a day (better more), lots of small companies here
don't have quick support, they would just wonder why they can't work
for one hour. That's quicker than most external IT support companies
have as reaction time to look at the customers servers.

That's what I mean. It has to be transported over media into the admins
ears and brains, that you will be blacklisted if your DNS setup is

And when there are problems because of bad DNS configs, somebody has to
step on the admins toes. I'm not a DNS guru, and I'm sure somebody will
