Authorities have not specified the cause of the interruptions. The Department of Homeland Security warned of the increased risks of cyberattacks on 911 services as they move to Internet-based systems.
There is no indication that the failures were caused by a cyberattack or other malicious act. Many of the service outages recorded in Nebraska, Nevada, South Dakota, and Texas, were fixed that same afternoon. The Federal Communications Commission (FCC) wrote on social network X on Thursday: "We are investigating" "Everyone who contacted us during the outage has been called back and provided assistance." Las Vegas Metropolitan Police said around 7 p.m. (local time) Locals were urged to dial 911 on cell phones, which they were able to see and call back, and insisted that calls from landlines were "not working at this time." "Texting 9-1-1 is working in most locations" as an option for contacting authorities.
