Here is a question most people have never considered: if your internet went down for a week, could you still access the information you need?
Not social media. Not entertainment. The information that actually matters: how to treat a burn, what your medication interacts with, how to shut off your home's gas valve, what the evacuation routes are for your area, how to purify water, what your rights are during an emergency declaration.
For most households, the answer is no. Everything lives online. And "online" is not as permanent as we treat it.
Why This Matters Right Now
The Department of Homeland Security has issued a National Terrorism Advisory System Bulletin warning that cyberattacks against US networks by pro-Iranian actors are likely during the current conflict. Iran-linked hackers have previously targeted American hospitals, water facilities, and banking systems.
A sustained cyberattack on internet infrastructure is unlikely to take down the entire internet. What it can do is degrade service: slower speeds, regional outages, intermittent connectivity. The kind of disruption where your phone shows one bar and nothing loads.
But you do not need a cyberattack to lose internet access. A severe storm, a damaged cable, a power outage lasting more than a few hours (once your router's battery backup dies), or simple network congestion during a regional emergency can all cut you off.
The question is not whether you will ever lose internet access. The question is whether you have what you need when you do.
The Offline Information Kit
Think of this as the digital version of the Hard Copy thesis: if the system that delivers your information goes down, do you have a backup?
Here is what to include and how to set it up.
1. Offline Wikipedia (Kiwix)
What it is: Kiwix is a free, open-source application that lets you download and browse Wikipedia (and other reference sites) entirely offline. No internet required. It works on Windows, Mac, Linux, Android, and iOS.
What it takes: All of English Wikipedia with images is roughly 90GB. Without images, it is about 22GB. Either fits on a USB drive or an external hard drive. The text-only version fits on most modern phones.
How to set it up:
- Go to kiwix.org
- Download the Kiwix app for your device
- Download the English Wikipedia file (called a ZIM file)
- Open it in Kiwix
That is it. You now have the entirety of human knowledge on Wikipedia accessible without any internet connection.
Why it matters: Wikipedia is not just trivia. It contains medical references, first aid procedures, information about medications and drug interactions, geographic data, emergency management protocols, and explanations of virtually every topic you might need during a crisis. It is the world's most comprehensive general reference, and you can carry it in your pocket.
2. Offline Maps
Google Maps: Open Google Maps on your phone. Tap your profile picture. Tap "Offline maps." Select the area you want to download. You can download maps for your city, your state, and your evacuation routes.
HERE WeGo: A fully offline navigation app. Download entire countries or regions for turn-by-turn navigation without any data connection. This is genuinely useful during an evacuation when cell networks are congested.
What to download:
- Your metropolitan area
- Your evacuation route(s) and destination(s)
- The area around any family members you might need to reach
- One state-level or regional map covering your likely travel radius
3. Offline First Aid and Medical References
American Red Cross app: Download the official Red Cross First Aid app. It includes step-by-step first aid instructions, a hospital finder, and emergency information that all work offline once downloaded.
First Aid PDF: Download and save a comprehensive first aid guide as a PDF. The Red Cross, St. John Ambulance, and WHO all publish free ones. Store it on your phone and on a USB drive.
Medication reference: If anyone in your household takes medication, save the drug information pages (from drugs.com or similar) as PDFs. Include interactions, side effects, and what to do if a dose is missed. This is especially important if you are taking multiple medications.
4. Emergency Management Guides
Your state's emergency management agency publishes guides specific to your area: evacuation zones, shelter locations, local hazards, and emergency contact numbers. Download these as PDFs now.
FEMA publications: Ready.gov has downloadable guides for virtually every emergency type. They are designed for households and are available as PDFs.
Local utility emergency information: Your power company, gas company, and water utility all publish emergency procedures. Download or print these.
5. Critical Documents on a USB Drive
This is the digital backup layer for your physical emergency binder:
- Scanned copies of IDs (driver's license, passport, birth certificates)
- Insurance policy documents
- Medical records and medication lists
- Property deeds or lease agreements
- Photos of your home's contents (for insurance claims)
- A copy of your emergency communication plan
Encrypt the USB drive. Both Windows (BitLocker) and Mac (Disk Utility) can encrypt USB drives with a password. This protects your personal information if the drive is lost.
Store the USB drive with your emergency binder or in your go-bag.
The 30-Minute Setup
Here is the priority order if you only have 30 minutes:
- Download offline maps for your area and evacuation routes (5 minutes)
- Download the Red Cross First Aid app (2 minutes)
- Save your state emergency management guide as a PDF (5 minutes)
- Start the Kiwix/Wikipedia download (it will run in the background for hours, but the setup takes 5 minutes)
- Copy critical documents to a USB drive (15 minutes)
If you have more time, add the medical references, utility emergency guides, and additional map regions.
The Physical Layer Still Matters
Everything above is digital, which means it still depends on a device with battery power. This is why the physical emergency binder remains the foundation. Paper does not run out of battery. Paper does not need Wi-Fi. Paper works when the power has been out for three days and every device in your house is dead.
The offline information kit is the middle layer between "everything online" and "everything on paper." It gives you the depth of digital resources (you cannot print all of Wikipedia) with the resilience of not needing a network connection.
The ideal setup:
- Paper binder: Critical contacts, medical info, financial info, communication plan, cash
- USB drive: Scanned documents, photos, digital backups
- Phone/tablet: Offline maps, Wikipedia, first aid app, state emergency guides
Three layers. Three levels of resilience. If any one fails, the other two still work.
The Broader System
This offline kit is one component of household resilience. The 90/14/500 buffer covers your immediate physical needs. The medication plan secures your prescriptions. The offline kit secures your access to information.
If you want to build the complete system, the free risk assessment at hrdcopy.com identifies your household's specific vulnerabilities and generates a tailored emergency manual that covers all of it: medical records, financial documents, communication plans, evacuation procedures, and the infrastructure documentation that ties everything together.
Your internet access is not guaranteed. Your information access can be.
