The Towers Were Standing: A Cause Decomposition of Cellular Outages During Hurricane Helene

A study on cellular outages during Hurricane Helene, which resulted in the largest recorded cell-site outage, reveals that the conventional assumption of physical damage to towers is largely incorrect. The research, based on FCC data, indicates that only a negligible percentage of outages were due to cell site destruction. Instead, power failures and severed transport (backhaul) infrastructure were the dominant causes, with geographical variations influencing their respective impacts.

This research provides critical insights into the actual causes of widespread communication infrastructure failures during extreme weather events, challenging conventional assumptions about physical destruction. Understanding these underlying vulnerabilities is essential for developing more resilient communication networks, improving disaster preparedness, and ensuring continuity of service for public safety and economic stability.

Hurricane Helene caused the largest absolute cell-site outage in public FCC records, peaking at 4,562 sites.

Forward consideration, not a verified fact.
