The outage occurred on December 21, 2022, killing calls to Verizon's VoLTE operations in six states for 1 hour 44 minutes, failing to connect hundreds of callers to 911, violating obligations.
FCC found the December outage due to poorly named software, not Verizon's mitigations; root cause was buggy security policy, replaced but not deleted, showing insufficient naming protocols leading to the outage.
Verizon fined $1.05 million by FCC, instructed to develop compliance plan including checklists for employees, testing network changes, and ensuring proper oversight to prevent future outages.
