Cost of Downtime can be classified as .

The cost of downtime is a critical metric in data center operations and business continuity planning. It is universally classified into two primary categories: direct and indirect costs. Direct costs are the tangible, immediate financial losses incurred during an outage, such as lost revenue, regulatory fines, and costs for repair and recovery. Indirect costs are the less tangible, long-term consequences, which can include damage to brand reputation, loss of customer confidence, reduced employee productivity, and supply chain disruptions. A comprehensive Business Impact Analysis (BIA) requires quantifying both types of costs to understand the full financial impact of a service interruption.

B. Up and Down: These terms describe the operational status of a service or system (i.e., uptime and downtime), not a classification of financial costs.
C. Mean and Median: These are statistical measures used to find the central tendency in a dataset; they do not classify the components of a single cost event.
D. Classified and Declassified: This terminology relates to the security and confidentiality levels of information, not to financial accounting for downtime costs. ---

University of California, Berkeley. (n.d.). Business Impact Analysis. UC Berkeley Information Security Office. In the BIA process documentation, costs are broken down into quantifiable (direct) and unquantifiable (indirect) impacts, such as "loss of public reputation or goodwill." This aligns with the direct/indirect classification. (Accessed via Berkeley's public-facing business continuity planning resources).

European Journal of Information Systems, 18(2), 106–125. https://doi.org/10.1057/ejis.2009.6. This paper, in its discussion of the costs of security breaches (a form of downtime), distinguishes between direct costs (e.g., "cost of repair") and indirect costs (e.g., "loss of future business," "loss of reputation").

Schneider Electric. (2012). White Paper 81: The Cost of Downtime. In Section "Tangible and Intangible Costs" (Page 2), the document explicitly states, "The costs of downtime can be broken down into two main categories: tangible costs (direct) and intangible costs (indirect)." It then provides examples such as lost revenue (tangible/direct) and customer loss (intangible/indirect).
