AT&T Outage Disrupts 92 Million Calls, Including 25,000 to 911

FCC report reveals a misconfigured network update led to a nationwide service disruption affecting emergency services and millions of devices.

The February 22 outage blocked voice and 5G data services for over 125 million devices in all 50 states and territories.
AT&T's failure to follow established procedures and conduct proper testing led to the network entering 'protect mode.'
The incident highlighted systemic issues within AT&T's processes, including inadequate peer reviews and insufficient safeguards.
Emergency services and FirstNet users were significantly impacted, with thousands of 911 calls unable to connect.
The FCC has referred the matter to its Enforcement Bureau, potentially resulting in penalties for AT&T.
