Incident Summary:
On March 10, 2026, Brillium experienced an unplanned service disruption during a scheduled platform upgrade. While Brillium upgrades are typically completed without customer impact and undergo extensive testing, this release resulted in unexpected performance issues that temporarily affected platform availability for our customers.
Our engineering team responded immediately, worked continuously to restore service, and progressively brought customers back online while stabilizing platform performance. The platform is now fully available and operating as expected for all customers.
Customer Impact:
During the incident, customers may have experienced:
We recognize the importance of platform availability to our customers’ assessment and testing operations and regret the disruption this incident caused.
Root Cause (High Level):
This release introduced new features that required updates to the platform’s underlying data structure, including initializing certain data values as part of the upgrade process. While the upgrade was aggressively tested prior to deployment, the testing did not fully account for the impact of these changes on customers with very large data volumes.
Under those conditions, the upgrade process placed significantly more load on the system than anticipated, which led to degraded performance and ultimately caused platform instability.
Resolution:
To resolve the issue, Brillium’s engineering team implemented targeted adjustments to support the upgrade process at scale, restored customer access in controlled phases, and increased monitoring to ensure platform stability. Once all customers were back online, the platform continued to be closely monitored to confirm normal operation and performance.
Preventative Measures and Improvements:
As a result of this incident, Brillium is implementing the following improvements:
These actions are intended to further reduce the risk of future upgrade related service disruptions.
Closing Statement:
We sincerely apologize for the disruption caused by this incident and appreciate the patience shown by our customers throughout the restoration process. Over the past 24 months, Brillium has successfully delivered more than 28 platform upgrades without service interruption through our zero downtime delivery process, which is designed to minimize customer impact.
While we take extensive measures to ensure reliable and seamless upgrades, unplanned issues can still occur in complex technology environments. We take this incident seriously and are applying the lessons learned to further strengthen our upgrade and testing processes. Brillium remains fully committed to providing a stable, secure, and continuously improving platform, and we thank you for your continued trust.
