I can't speak for Mark, but many businesses that lose significant Google traffic do use Adwords campaigns to support their revenue as tehy wrok to recover from the downtime. It's often not as profitable as organic, but it's a lot better than closing your doors. I often suggest that some funds be set aside for PPC when a major re-design is being planned - and especially a domain migration. But the same principles apply to any loss of income from search traffic.
