Losing millions of dollars. Very nicely said.
Then there are those that move their website, with their DNS, to a
different provider, and are then confused as to why their email is
broken. Of course it is the email providers fault, and they have no
comprehension that it might somehow be related to the recent changes
with their website.

That’s all good and fine for your DNS, but it did nothing for me when Peter
from www.BeckmanPimpsStereos.com was calling every 3 minutes screaming that his
web site has been down for a day and that he’s losing “millions of dollars”,
all because we just had to migrate his ColdFusion site off a yellowing-beige
NT4 box running vintage IIS to PrimeHostOutsourcerOne and now all the locals on
DopeCable can’t access it…

Hahaha yeah, thanks Residential ISPs, your DNS sucks. I always found a
better caching resolver, like UUNET, until Verizon got better at it, and
then Google DNS came along.
The caches have cleared.

Why, back in my day, residential ISPs would ignore your TTLs and cache for 3
days no matter what you did…

Please, y'all -- when doing a DNS migration, ensure 1000% that your DNS
records on your old DNS provider match your DNS records on your new DNS
provider, and plan your DNS migration early by setting the TTL for your NS
records at least to 5 minutes (300 seconds) if allowed, 30 seconds if you
can.
Assume all caching servers will cache for 5 minutes even if you set it to
30 seconds.
At least that way if things go wrong, your outage horizon is 5 minutes, not
1 hour or more!!!
