Explanation

Human error is the leading cause of data center downtime, responsible for roughly 70-75% of outages according to industry studies - this includes misconfigurations, incorrect procedures, failed updates, and accidental deletions that cascade into major failures. Equipment failure (D) does occur but ranks second, and modern redundant hardware design has significantly reduced its impact. Natural disasters (C) are rare, geographically concentrated, and mitigated by geographic redundancy and disaster recovery planning, making them a minor contributor overall. Sabotage (A) is exceedingly uncommon and accounts for a negligible fraction of incidents compared to everyday operational mistakes.

Memory tip: Think "people break things more than machines do" - the human-in-the-loop is always the weakest link. Remember the acronym H.E.A.D.S UP: Human Error Always Dominates Statistics.
