The Hidden Costs of Downtime 2026
A $600 billion wake-up call, in partnership with Splunk
Oxford Economics and Splunk captured responses from 2,000 executives from Global 2000 companies to analyse the immediate and long-term effects of downtime triggered by cybersecurity incidents.
Downtime has stopped being just an IT headache and become a boardroom crisis. As organisations lean further into interconnected digital ecosystems — third-party vendors, cloud providers, and now autonomous AI agents — every new link becomes another point of failure, and the fallout from a single outage spreads faster and farther than ever. Splunk’s research with Oxford Economics reveals the scale of that spread: outages now ripple into regulatory fines, ransomware payouts, stock price dips, and reputational damage.
This report invites the reader to uncover where outages actually originate, from everyday human error to sophisticated cyberattacks, and why the toll is proving harder to contain. You’ll see how AI is reshaping the equation, helping teams resolve incidents faster while introducing new failure modes of its own. Readers will also find strategies resilient organisations are using to treat downtime as a business risk and build the kind of predictive immunity that separates market leaders from the rest.
