AT&T and 3G Network Shutdown: AT&T is shutting down its 3G network to make way for 5G. If you're using an older phone for emergencies, you might no longer be able to dial 911 — even without a subscription, you still need a signal. Check with your provider to see if a software update or new device is needed. Other services like e-readers, vehicle safety systems, home alarms, and medical alert devices could also be affected.

Chicago has launched the first public utility microgrid cluster in the U.S. The Bronzeville microgrid includes solar panels, battery storage, and natural gas generation, designed to provide power during emergencies like extreme weather or cyberattacks.

Opinion: Some experts are suggesting that the future of urban living might lie underground, offering safer and more resilient alternatives.

Tonga has restored internet connectivity to its main island five weeks after a deadly volcanic eruption. Over 56 miles of undersea cables were repaired, and Starlink is being used to help reconnect remote islands.

A Canadian sailor survived six days adrift at sea after his boat sank. He managed to grab essential supplies, including a computer, water, flares, and a personal locator beacon. His advice? “It’s the panic that kills you.”
