Yeah, makes sense if explicitly stated. Not everything is worth the money.

However, in my experience, the people doing the calculations on that risk have no incentive to cover it. Their bonus has no link to the uptime and they can blame $INFRA for the lost millions and still meet their targets and get promoted / crosshired.

The people who warned them and asked for funding are the ones working late and having conf calls with the true stakeholders.
