Briefings
Two technical failures in 48 hours exposed digital infrastructure vulnerabilities, causing widespread disruptions to Microsoft 365 services and US air traffic control systems. The incident highlighted critical gaps in cyber insurance coverage, with estimates ranging from 300 to 1.4 billion USD in potential insured losses. While some insurers like Marsh Re and Morningstar DBRS suggest limited market impact, the FAA suspension of flights raised significant questions about whether public infrastructure failures fall under standard interruption coverage.
Key points
- Microsoft 365 services and US air traffic control communication systems experienced disruptions on November 13-14, 2026, affecting thousands of organizations globally.
- The FAA suspended flights due to a router installation failure by L3Harris, causing thousands of flight cancellations and delays that may not qualify for standard interruption coverage.
Context
This briefing examines two recent incidents where digital infrastructure failures exposed systemic risks to the insurance sector. The Microsoft outage and FAA air traffic control disruption occurred in November 2026, demonstrating how single points of failure can impact multiple industries simultaneously. These events challenge existing insurance models regarding coverage for public infrastructure failures and the ability of insurers to manage simultaneous global disruptions.
Limitations
Insurance loss estimates vary significantly between 300 million to 1.4 billion USD, reflecting uncertainty about deductible conditions and claim eligibility. Coverage limitations for public infrastructure failures remain unclear, and the FAA suspension duration extended beyond the initial five hours, complicating immediate claim assessments.
