We have completed the root cause analysis for this incident and would like to share it with you.
On January 10, 2022, customers hosted in the Ashburn (DC08) Data Center experienced a service disruption while accessing multiple SuccessFactors applications.
The disruption was caused by a network connectivity issue that continuously caused multiple network switches to restart. The constant restarting of the switches did not allow application requests to process.
As a result, the vCenter (central management utility used to manage virtual machines (VMs) from a centralized location) lost connectivity to the underlying storage devices causing all the VMs hosted in DC8 to become non-responsive.
The network team disabled an authentication configuration on the impacted switches to resolve the issue, which recovered the switches and restored network connectivity.
After the network resolution, Cloud Operations recovered the Center, then restarted all VMs in sequential order. The recovery process was complex due to several service interdependencies. After appropriate validation checks, Cloud Operations confirmed service restoration on January 10, 2022.
Root Cause Analysis:
The root cause of this incident has been attributed to a software defect on a specific version of the network vendor switch firmware. The vendor had recommended an iterative upgrade approach using the interim version of firmware as a first step, followed by an upgrade to the final firmware release. It was during this iterative approach/interim version, the defect was introduced and led to the network connectivity issue/service disruption for all SuccessFactors applications.
Measure #1: Upgrade the network vendor switch firmware to the final firmware release. (Completed: January 15, 2022)
Measure #2: Audit checks of the firmware version on all remaining network devices not affected by the issue, and an upgrade to final firmware version where required. (Target Date: February 25, 2022)
Measure #3: Future network switch upgrades to be performed after thorough verifications and checks by the network vendor. (Target Date: February 25, 2022)
Measure. #4: Create an automated service restoration process for data center level outages to restore services as quickly as possible if server restarts are required for resolution. (Target Date: February 17, 2022)
