NetOps in Action: Fidelity National Information Services, Inc. (FIS)

Fidelity National Information Services, Inc. (FIS) is an American multinational corporation which offers a wide range of financial products and services. FIS is most known for its development of Financial Technology, or FinTech. FIS has a portfolio of products for the financial services sector, including both retail and investment banking.

FIS global customers connect to services from FIS’s Little Rock, AR datacenter. Customers experienced degraded service over a period of several weeks, and efforts to isolate the root cause proved to be challenging for the FIS network operations teams, as it involved an intermittent manifestation of symptoms.

With AppNeta by Broadcom, however, FIS was able to isolate several Cisco switches with a unicast flooding defect.

Leveraging the visualized network delivery paths from Little Rock and monitoring points deployed across the enterprise network, the team was able to quickly observe spikes in data loss on network paths connecting to the Little Rock data center. Upon further investigation, running a TCP Dump from the AppNeta monitoring point highlighted the Unicast flooding received on the monitoring points network interface – transmitted in error by a Cisco defect on their switching IOS.

As a result, Cisco quickly prioritized the patching of their network switch operating system. After patching, Unicast traffic was no longer observed and the network delivery path showed improved data loss metrics (within threshold parameters).

Without the ability to isolate the root-cause, FIS global customers were at risk of continued service disruption. Continued issues could have exposed FIS to negative financial and reputational risks.

AppNeta’s ability to isolate and provide visibility into root-cause also supported the FIS Global business decision to expand AppNeta deployment to Australia and Brazil.
