Why Comms Fail
Understanding the failure modes of modern communication infrastructure and why single points of failure are everywhere.
Why Communications Fail
Modern communication infrastructure is remarkably fragile. Despite the appearance of redundancy, most systems share critical dependencies that can fail simultaneously.
The Illusion of Redundancy
Having multiple cell carriers doesn't help when all of them share the same fiber backhaul, the same power grid, or the same internet exchange points. True redundancy requires independence at every layer.
Most "redundant" systems are not truly independent. Cell towers, ISPs, and even satellite ground stations often share power, cooling, and physical infrastructure.
Common Failure Modes
Power Grid Failures
The most common cause of communication outages. Cell towers typically have 4–8 hours of battery backup. After that, silence.
Physical Infrastructure Damage
Hurricanes, earthquakes, and floods destroy towers, cut fiber, and flood equipment rooms. Geographic concentration of infrastructure amplifies the impact.
Network Congestion
During emergencies, everyone reaches for their phone simultaneously. Networks designed for average load collapse under crisis demand.
Cyber Attacks & Software Failures
BGP hijacks, DNS failures, and software bugs have taken down major internet infrastructure for hours at a time.
Regulatory & Jurisdictional Issues
Governments can and do shut down communications during civil unrest. Cross-border communication may be restricted or monitored.

Each link in this chain is a potential failure point. Resilient communication requires alternative paths that bypass as many of these dependencies as possible.
The goal isn't to eliminate failure — it's to ensure that no single failure leaves you completely unable to communicate.
