The most costly data center outage over the past two years cost the company operating the data center about US$1.02m, according to the latest survey by the Ponemon Institute, sponsored by Emerson.
The survey analyzed downtime costs at 41 US data centers, with data center floor size of 2,500 sq ft and up, over the past two years. The institute looked at costs associated with impact on productivity, legal and regulatory consequences, as well as lost confidence and stakeholder trust, among other costs.
Here is a chart, breaking down cost sources in an average outage:

The $1.2m figure mentioned above is at the top of the range. The outage where the company ended up losing the least cost it about $39,000.
The survey concluded that the average cost of an outage was about $5,600 per minute, with cost systematically related to duration of the outage and size of the data center. The average incident length was 90 minutes.
Larry Ponemon, chairman and founder of the Ponemon Institute, said in a statement that today, with companies increasingly relying on IT systems to support business-critical applications, a single downtime event can have a significant impact on profitability and, in some cases, viability of an enterprise.
“An inadequate data center infrastructure will contribute to recurring downtime events and result in significant financial losses as well as permanent damage to a company’s reputation and customer goodwill,” he added.
Biggest incident causes were UPS battery failure (65%), exceeding UPS capacity (53%), accidental emergency power-off (51%) and UPS equipment failure (49%).
A total data center outage, with average recovery time of 134 minutes, cost about $680,000 on average. A partial data center outage, lasting 59 minutes on average, resulted in average cost of about $258,000.
The survey also concluded that IT equipment failure was the most expensive root cause, and accident and human error were least expensive.
