OrbusInfinity users may have experienced periodic and short spells of application latency and slow response times when logging in to OrbusInfinity for the first time. Some users may have experienced rare and occasional timeouts and received errors through the course of using the OrbusInfinity application.
Sporadic but large increases in application usage and traffic volumes resulted in an OrbusInfinity application service slowing down and eventually being auto restarted.
The service is configured to handle deviations from normal traffic volumes and system load with auto-scaling in place to account for the fluctuations. In this instance, the profile of the traffic did not trigger the auto-scale operations. The traffic volumes were extremely high but short in duration. This meant auto-scale trigger thresholds were not met over the course of the evaluation periods.
As part of remediation activities, Orbus engineers have updated the configuration for auto-scaling to better identify and react to the traffic volumes and profiles of this nature. Thresholds and evaluation periods have been adjusted accordingly meaning auto-scale operations are working as expected. This has been validated by engineers through the period of monitoring post incident.
