The Verizon Outage and the Cost of Concentration

The recent Verizon outage underscores a growing risk in today’s technology landscape: when critical services are concentrated among a small number of providers, failures don’t stay isolated.

In this live discussion, we’ll connect the Verizon outage to past telecom and cloud disruptions to examine how infrastructure dependency creates cascading business impact. We’ll also explore how large-scale outages intersect with security threats targeting telecommunications, where availability, confidentiality, and integrity failures increasingly overlap.

The session will close with actionable takeaways for strengthening resilience and risk planning across cybersecurity and IT programs.

 

Key Takeaways

1. Diversify your technology infrastructure. Relying on a single carrier, cloud provider, or bundled service creates a single point of failure. Purposeful diversification across providers can reduce the impact of large-scale outages and improve overall resilience.

2. Treat outages as security incidents, not just reliability problems. Large-scale telecom and cloud outages directly disrupt authentication, monitoring, and incident response, and should trigger security workflows—not just IT troubleshooting.

3. Identify and document your dependencies on carriers and cloud providers. Many security controls rely on SMS, voice, cloud identity, or single regions; understanding these dependencies ahead of time prevents dangerous blind spots during outages.

4. Plan and test incident response without phones, SMS, or primary cloud access. Assume your normal communication and authentication methods will fail and ensure your teams know how to coordinate securely when core services are unavailable.

5. Expect outages to increase fraud and social engineering activity. Attackers exploit confusion and urgency during service disruptions, so security teams should prepare staff for impersonation and “service restoration” scams during major outages.

6. Use widespread outages as learning opportunities. Review what happened, assess how your organization was—or could have been—impacted, identify potential areas for improvement, and update incident response, communications, and resilience plans accordingly.
