Investigation into Massive Cellular Outage in the US

Federal agencies are investigating a massive cellular outage in the US to determine if it was a cyberattack. The outage, affecting major carriers like AT&T, Verizon, and T-Mobile, may have been caused by a Distributed Denial of Service (DDOS) attack. Hackers could have gained access to customer call data records. The outage might also be attributed to cloud misconfiguration or human error.
