A fiber cut during highway construction severs Veritel's metro ring; a routing misconfiguration during reroute propagates the outage across the Southeast region. Branch WAN, ATM connectivity, and the primary data center's carrier path all degrade. The diverse carrier (SecondNet) auto-fails-over for ~80% of branches; the remainder and the ATM estate require manual cutover by field technicians.
