3 Ways Fiber Internet Saved Lives in Hawaii

On August 8, 2023, wildfires swept through Lahaina, Maui with terrifying speed. Driven by 60+ mph winds from Hurricane Dora, the fire destroyed over 2,200 structures and killed 101 people — the deadliest U.S. wildfire in more than a century. In the chaos, cell towers went dark. 911 systems failed. Wireless alerts never reached thousands of residents.

But for some households, something still worked: their home fiber internet connection.

This isn't a coincidence. Fiber internet has specific technical characteristics that make it more resilient in disasters than cable or wireless. Here are three reasons why — and what Hawaii residents can do right now to be better prepared.

Reason 1: Fiber Keeps Working When the Power Goes Out

Cable internet requires powered amplifiers and signal nodes distributed throughout the network — sometimes one every few hundred feet. When the electrical grid fails, those nodes go dark, and the entire cable network goes down with them. It doesn't matter if your modem has backup power; the infrastructure feeding it does not.

Fiber works differently. Fiber-optic cables transmit data using light signals — photons traveling through glass strands, not electrical current through copper wire. The outside plant (the fiber network between your home and the provider's central office) does not require local electricity to operate. Light doesn't need power lines.

The only piece of equipment at your home that needs power is the ONT — the Optical Network Terminal, a small device typically mounted near your utility box. And that's where a simple, inexpensive investment changes everything.

“Unlike cable internet, which relies on electricity at many points in the field, a fiber-optic network does not require electricity in the field to operate.” — Ziply Fiber

With a UPS (Uninterruptible Power Supply) connected to your ONT and WiFi router — a $50–$150 investment at any hardware store — fiber internet can continue working for 4–8+ hours during a power outage. The fiber network itself stays live. Your house stays connected.

During the Lahaina fires, electrical infrastructure was among the first to fail. Downed power lines — later implicated in starting the fires — caused cascading outages across the grid. Cable internet subscribers lost service almost immediately. Fiber subscribers with backup power kept their connections alive.

Note: Hawaiian Telcom's own battery backup equipment is designed to maintain phone service during outages. Customers who add a UPS to their ONT and router can extend this to include data and internet access as well.

Reason 2: A Stable Connection Meant Staying Safe — and Staying Informed

As Lahaina burned, residents had almost no way to know what was happening or where to go. The Maui Emergency Management Agency had posted a shelter-in-place alert on Facebook at 4:16 AM — hours before conditions became critical. But when fires swept through and cell towers went down, those social media updates, live news streams, and emergency websites became inaccessible to most.

For households with working fiber and a charged laptop or tablet, it was different. Internet access meant:

• Real-time road condition maps showing which routes were passable
• Family communication via WiFi calling and messaging apps
• Live news and fire tracking from county and state emergency sources
• Coordination with neighbors via neighborhood apps and group chats

The 2024 Hawaii Attorney General report on the Maui fires documented how “inoperative cell towers left residents and tourists with little options to receive emergency alerts like evacuation orders.” AP News documented the communications chaos — no sirens, no wireless alerts, no way for many residents to know the fire was coming. Those who escaped often did so on instinct or because a neighbor knocked on their door.

An internet-connected household could receive real-time updates from sources entirely outside the cellular network. In a disaster where official alert systems completely failed, that access was genuinely life-or-death.

Reason 3: Speed and Reliability That Didn't Fail When It Mattered Most

In an emergency, bandwidth isn't just about convenience. Loading a live fire map, streaming a news broadcast, or video-calling 911 when voice lines are jammed all require real throughput — and reliability.

Fiber internet's symmetrical speeds matter here. You can upload a location pin, a photo, or a video call as quickly as you can download information. Cable's asymmetric design — typically 10–50 Mbps upload versus 300–1000 Mbps download — becomes a meaningful disadvantage when you're trying to send emergency communications outward.

Beyond speed, fiber is fundamentally more reliable than cable. Cable connections degrade with distance, with neighborhood congestion, and with physical damage to copper wire. Fiber signals travel through glass and are immune to electromagnetic interference. During a storm or disaster, that reliability isn't academic — it's the difference between a connection that holds under pressure and one that drops exactly when you need it.

Latency matters too. Fiber's typical latency of 5–15ms (versus 15–35ms for cable) means faster response times for voice calls and video — critical when every second counts in an emergency situation.

What You Can Do Right Now

You can't control when emergencies happen. But you can control how prepared your home is.

• Switch to fiber if it's available at your address. Hawaiian Telcom Fioptics delivers 100% fiber to homes across Oahu, Maui, the Big Island, and Kauai — with speeds up to 3 Gig and symmetrical uploads.
• Add a UPS to your ONT and router. A $50–$100 uninterruptible power supply keeps your home connection live for hours if the grid goes down.
• Download offline maps and emergency contacts before a disaster. Apps like Maps.me and Google Maps allow offline use when you're away from WiFi.
• Enable WiFi calling on your phone. When cell towers are down but your WiFi is up, WiFi calling keeps your phone working over your home internet connection.

Fiber isn't just fast internet — it's infrastructure. In a place as geographically isolated as Hawaii, where natural disasters are not hypothetical but recurring, the internet technology you choose is part of how you prepare. Cable was built for broadcasting television. Fiber was built for two-way communication that survives. The Lahaina fires showed, in the most devastating way possible, that the difference matters.
