Back when we had servers in an onsite DC we lost a raid card and the system I was developing went down. We had the fancy support so a tech was out with the card replaced in a couple hours, then we had to restore from tape backup. All in all, a non-critical system was down for most of a business day. My bosses boss stormed in, upset he couldn't pull a report, and asked how do we prevent this in the future. I responded at a minimum we had to double the cost for a hot standby, and he said 'never mind' and walked out.
