AT&T failed to test disastrous update that kicked all devices off network
AT&T caused outage that blocked 92 million calls, 25,000 attempts to reach 911.
At 2:42 am CST on February 22, an AT&T “employee placed a new network element into its production network during a routine night maintenance window in order to expand network functionality and capacity,” the FCC said. The configuration “did not conform to AT&T’s established network element design and installment procedures, which require peer review.”
An adequate peer review should have prevented the network change from being approved and from being loaded onto the network, but this peer review did not take place, the FCC said. The configuration error was made by one employee, and the misconfigured network element was loaded onto the network by a second employee.
“The fact that the network change was loaded onto the AT&T Mobility network indicates that AT&T Mobility had insufficient oversight and controls in place to ensure that approval had occurred prior to loading,” the FCC said.
