Norfolk Southern Blames Outage on Vendor Software

Norfolk Southern is attributing a recent system outage to a
defect in the software of a vendor that performs maintenance on its
data-storage system.
The railroad operator said it has finished a root-cause analysis
of Monday's outage and found no indication that it was related to
an unauthorized cybersecurity incident.
During a routine maintenance procedure performed by a vendor,
the vendor's software created an error that caused the company's
primary and recovery data-storage systems to become unresponsive,
which then affected its core operational systems. Norfolk Southern
didn't name the vendor but described it as a "leading global
technology provider."
"We are working closely with the vendor to understand the steps
they are taking to strengthen their systems to prevent this
incident from reoccurring and identify opportunities for Norfolk
Southern to become more resilient," the company said.
Norfolk Southern is making progress on the temporary backlog of
trains caused by the incident and expects network fluidity to fully
recover in the coming weeks.
