A viral warning circulating on social media claims that a worldwide blackout could occur on November 17, 2026, leaving millions of people without electricity, internet access, banking services and communications for 72 hours.
The rumor appears to combine an actual U.S. emergency alert test with scenes from the animated television series The Simpsons, creating a misleadingt connection between two unrelated events. Boatos+2
Did The Simpsons predict the blackout?
The viral theory references an episode titled It’s a Blunderful Life, from Season 35, originally broadcast in November 2023.
In the fictional storyline, Lisa recalls a blackout affecting Springfield, the show’s fictional town.
Although the episode contains a power outage, it does not predict a worldwide blackout on November 17, 2026, nor does it describe a global internet or banking shutdown.
FALSE — NO EVIDENCE
However, there is no credible evidence of a planned global blackout or a government-ordered shutdown of electricity, internet or banking systems.
A test of emergency alert systems does not mean that electricity, internet connections, mobile phone networks, or banking systems will be turned off.
What will actually happen on November 17?
According to the official Federal Emergency Management Agency (FEMA) and Federal Communications Commission (FCC) announcements on September 16, 2026 public notice:
- Date: Tuesday, November 17, 2026.
- Time: 2:20 p.m. Eastern Time.
- Purpose: Nationwide testing of the Emergency Alert System (EAS).
- Coverage: Participating radio, television, cable and satellite providers across the United States.
- Duration: The interruption to regular radio and television programming is expected to last approximately one minute.
- Cell phones: Wireless Emergency Alerts are not included in this year’s test.
- Public action: None required.
The purpose is to verify that the country’s emergency alert infrastructure can distribute public warnings when needed.
The test will be conducted in English and Spanish.
Why are people talking about 72 hours?
The 72-hour reference comes from general emergency preparedness recommendations encouraging households to maintain essential supplies in case of natural disasters or temporary disruptions.
It is not evidence of a scheduled blackout.
GBC News — Final Fact-Checking Verdict
The claim that the world will experience 72 hours without electricity, internet or banking services on November 17 is false and unsupported by credible evidence.
The only confirmed nationwide event associated with that date is the scheduled U.S. Emergency Alert System test.
There is no reason to panic or make emergency purchases based on this viral warning. As always, it is important to verify alarming claims through official sources before sharing them.
The U.S. emergency alert test is real. The alleged global electricity and internet shutdown is not.
The public should avoid spreading unverified warnings that could create unnecessary panic.
