You can often get away with some downtime, but that's not the same as not spending any engineering effort.
What kills you is when you take an hour scheduled downtime, communicate this out, get everyone on board... and then are down for a day. If you don't have a good, well-rehearsed, plan, you might be unexpectedly screwed even then. As a rule of thumb... something usually doesn't quite go how you expect it to!
- ohyeshedid 5y agoTo your point: You can have the best plan in the world, well rehearsed and battle tested; something in that last patch bugged out and took the system with it. Now you're getting cursed out because the email, ivr, etc all said 1 hour downtime and it's been 4. Weekly scheduled downtime has value, but it's not a good idea for most.
