Quick Stats/Facts Box – Number of Companies Affected, Estimated Losses

Understanding the scale and impact of the October 2025 AWS outage is essential for assessing the adequacy of existing insurance policies and identifying potential coverage gaps. As businesses increasingly rely on cloud services, it’s crucial to evaluate whether current cyber insurance policies adequately cover losses resulting from such outages. This analysis will help inform decisions about policy adjustments and risk mitigation strategies. 

Understanding the Insurance Landscape for Cloud Outages

Cyber insurance alone often doesn’t cover cloud outages like AWS disruptions. Businesses need to understand the nuances of Cyber Insurance, Dependent Business Interruption (DBI), and emerging Cloud-Downtime policies to ensure comprehensive protection.

Cyber Insurance: Coverage Triggers & Standard Clauses 

Cyber insurance typically covers losses from cyberattacks, data breaches, and system failures. Coverage for cloud outages varies:

• Trigger Events: Policies may specify triggers like “security failure” or “system failure.” If the outage is due to a system failure without a security breach, coverage might not apply.

• Waiting Periods: Many policies have waiting periods ranging from 8 to 12 hours. Shorter outages may not be covered.
• Sub-Limits: Some policies impose sub-limits on dependent outages, meaning coverage is capped even if actual losses exceed that amount.

Dependent / Contingent Business Interruption (DBI/CBI) 

Dependent Business Interruption (DBI) insurance covers losses when a business is disrupted due to issues with a third-party provider, like a cloud service. This coverage is crucial for businesses relying on AWS or similar providers.

• Coverage Scope: DBI policies can cover lost income, extra expenses, and reputational damage from third-party service disruptions.

• Policy Variations: Coverage varies by policy. Some only cover IT-related disruptions, while others include non-IT vendors. Reviewing policy limits and exclusions is essential.

Cloud-Downtime / Parametric Insurance 

Cloud-Downtime or Parametric Insurance addresses gaps in traditional cyber insurance.

• Automatic Triggers: Policies pay out automatically when predefined conditions occur, such as a cloud outage exceeding a set duration.

• No Proof of Loss Needed: Payouts are based on the event, not on proving the exact loss.

• Customization: Policies can be tailored to specific cloud providers and services.

Comparison Table: Cyber vs DBI vs Cloud-Downtime Policies

Next Step: Review your current insurance policies to identify gaps. Consult your broker to explore options for enhancing coverage, especially if your business relies on AWS or other cloud services. 

Quick Tip

For comprehensive protection, combine Cyber Insurance with DBI and Cloud-Downtime policies. This layered approach ensures coverage for internal system failures, third-party disruptions, and cloud outages.

Would Your Policy Cover an AWS Outage? Reality Check

Most standard cyber insurance policies will not fully cover losses from an AWS outage. Coverage depends on the policy’s wording, triggers, and exclusions. Businesses often assume their cyber insurance protects against any IT disruption, but cloud outages caused by a vendor failure are usually excluded unless explicitly included through Dependent Business Interruption (DBI) or specialized cloud-downtime coverage. 

Key Policy Definitions and Triggers 

• System Failure vs Security Breach: Policies typically cover losses caused by malicious attacks or system compromise. Pure downtime from a cloud provider may not qualify. 

• Waiting Periods: Many policies have waiting periods ranging from 8 to 12 hours. Shorter outages may not be covered. 

• Sub-Limits: Some policies impose sub-limits on dependent outages, meaning coverage is capped even if actual losses exceed that amount. 

Common Exclusions to Watch For 

• Third-party service failure (AWS, Azure, Google Cloud) 

• Scheduled maintenance or planned downtime 

• Losses from indirect or reputational impact, unless specified 

Real-Life Example: October 2025 AWS Outage 

During the AWS outage, several businesses reported multi-hour downtime. Companies with only standard cyber insurance often received no payout, while those with DBI or parametric cloud-downtime policies had partial to full coverage, depending on trigger definitions and payout terms. 

Quick TIp

Always review your policy for third-party coverage and cloud vendor dependency clauses. If gaps exist, ask your broker about adding DBI or parametric coverage to protect against future cloud outages.
