On Thursday, September 25, 2025, emergency 911 services across Louisiana and Mississippi were disrupted for over two hours due to damage to AT&T fiber optic lines. The outage sparked immediate concern among public safety officials and residents alike, highlighting vulnerabilities in the nation’s emergency response infrastructure.
What Happened?
According to state officials, the disruption began in the early afternoon and lasted more than 120 minutes. The cause: multiple cuts to AT&T’s fiber optic network, which carries critical 911 call routing data for both states.

State Responses
Mississippi Governor Tate Reeves confirmed the issue stemmed from “a series of fiber cuts” affecting AT&T’s backbone network. The Mississippi Emergency Management Agency (MEMA) activated backup protocols, urging residents to use non-emergency police lines or go to the nearest station if possible.
Louisiana officials reported similar disruptions but noted that rural areas—where 911 relies heavily on a single telecom provider—were hit hardest.

Why This Matters for Public Safety
The incident underscores a growing concern: overreliance on a single telecom provider for emergency infrastructure. Unlike traditional landlines, modern 911 systems often depend on internet-based (VoIP) networks that are vulnerable to physical and cyber disruptions.

AT&T has launched an internal investigation and pledged to work with state authorities to prevent future outages. The FCC is also expected to review the incident as part of its ongoing oversight of emergency communications.
