Management that has "moved into the modern digital world" would already
understand that 100% uptime is an impossible business requirement.
Airplanes crash, nuclear power plants trip offline, heart attack victims
die in the emergency room -- there is no such thing as 100% uptime. And
"five nines" is probably way more expensive than any conceivable cost
that your customers are incurring due to an occasional outage of your
site. It's frustrating when management tries to scapegoat the techies
for its own inability or unwillingness to manage the risks of the
business appropriately.
I was still somewhat shocked, however, when one of the largest banks in
the world recently sent me an e-mail, as one of their credit card
customers, informing me that their on-line account management site would
be down for ONE FULL WEEK due to a system upgrade!!! It's hard for me
to imagine how even the sloppiest, most poorly run little software shop
couldn't do better than that...
