Valerie knows that her organization’s datacenter power infrastructure has an MTTR of 24 hours. What should she do if there is a critical component failure in her power infrastructure, and the organization has a warm site with an activation of 12 hours and needs to be back online as soon as possible?

Valerie should immediately begin a move to the warm site. She knows that moving to her warm site takes half the average time to repair for her datacenter’s power infrastructure. That means that in most cases, moving will result in at least a 12-hour shorter outage. If the time to repair proves to be shorter than 12 hours, she can simply stop the move. Waiting does not restore her to operation sooner than 24 hours in the average case, and waiting to make the decision reduces the amount of advantage she gets from moving to the warm site.
