When warnings are taken seriously, and no disaster happens: Clearly, the warnings were unnecessary. When warnings are not given and a disaster happens: clearly the team was incompetent and should have seen it coming. When warnings are not given or ignored and no disaster happens: they were overblown and pointless, why do we even have a disaster recovery team. When warnings are taken seriously and a disaster still happens: it's the worst of both worlds. You can't win in this situation. No combination of warning/not warning and disaster/no disaster results in success. If you can't trust your managers to cogently weigh the risks and costs, there's nothing you can do.
