Does Cyber Insurance Cover a Cloud Outage Without a Cyberattack?
Yes—some cyber policies can cover a cloud provider’s accidental outage without a cyberattack. The purchased coverage must address the relevant dependent or contingent system failure; a cyber limit alone does not confirm that protection. Before renewal or a hosting migration, check the outage cause, qualifying provider, waiting period and covered loss calculation.

1. Ask about accidental failure, not just cyberattacks
Hypothetical example: Your cloud provider makes a configuration mistake that interrupts your SaaS platform for ten hours. No attacker is involved and no data is stolen. Usage-based transactions stop while engineers build a workaround. Present that scenario during renewal rather than asking only whether the policy covers cloud outages.
Beazley’s U.S. MediaTech for Small Businesses page lists dependent business interruption arising from a security breach or system failure. That is a product-specific example, not confirmation that every cyber policy includes both causes.
Ask the broker to identify the provision that would address the provider’s accidental mistake. Have the explanation connect the coverage grant, definitions and endorsements to your scenario. Treat an unresolved trigger as an open coverage question—not as confirmation.
2. Confirm that the provider and service qualify
Corvus’s coverage explainer identifies possible restrictions involving eligible service categories, specifically named vendors and infrastructure exclusions affecting internet service providers or the electrical grid. These are wording checks, not universal exclusions.
Build a dependency list from your own architecture: production hosting, managed databases, authentication and other external services essential to delivering the product. Record the contracting entity and what stops working when each service fails.
For a hosting migration, review the proposed arrangement rather than copying last year’s provider list. Ask whether each service qualifies and whether the policy requires it to be named. Flag dependencies on a provider’s subcontractors for separate review.
