Helpful prompt about what to do if the internet goes down due to a global cyberattack/AI swarm. This seems less insane with every passing day. I also bought myself the SAS Survival Guide, which is essentially a bush manual for almost every imaginable outcome. Money - Keep cash at home, about two to four weeks of essentials, in small bills. - Write down your bank, credit card and insurance account details and phone numbers on paper. Information and contacts - Print a contact list with family, close friends, neighbors, doctors and the kids’ school. - Agree on a family meeting point and plan in case phones are down, such as “if we can’t reach each other, meet at X by Y time.” - Export and print or save offline anything business-critical. - Download offline maps - Keep paper copies of passports, IDs, insurance cards and prescriptions. Communication - Get a battery or hand-crank AM/FM/NOAA radio, which will be your main news source. - Consider a pair of walkie-talkies or GMRS radios for the family. - Keep a landline-style backup in mind. Most “landlines” now run over the internet, so don’t count on yours. Power - Keep power banks charged, plus a solar charger or a larger portable power station. - Have flashlights, headlamps and spare batteries. Water and food (aim for 2 weeks) - Store about 1 gallon of water per person per day. In a high-rise this matters most, because building water pumps need electricity. - Stock shelf-stable food the kids will actually eat, plus a manual can opener. - Keep a camping stove with fuel for outdoor or ventilated use only, or no-cook foods. Health - Keep at least a 30-day supply of any prescriptions. - Have a first aid kit, OTC basics like pain relievers in children’s doses, and hygiene supplies. Home and offline life - Learn how to manually open anything electronic, such as smart locks and the building’s garage or entry. - Keep a paper copy of the building’s emergency procedures and super’s number. - Download offline entertainment and learning material for the kids: books, games, art supplies. - Get to know a few neighbors, since local community becomes your network fast. Digital hygiene (helps before and after) - Back up photos and documents to an external drive kept offline. - Use strong, unique passwords with 2FA, and keep printed recovery codes for key accounts.
