Is Brillium down?

Unplanned Maintenance & Temporary Configuration Update for AI Essay Grading Service Effective Dates: Thursday, May 21, 2026 – Monday, May 25, 2026 At Brillium, we are committed to providing you with the highest standard of reliability, performance, and innovation. To ensure our platform continues to leverage the most robust, secure, and advanced technology available, we are currently updating the underlying language models that power our AI Essay Grading service. What is Happening? Following a planned technology deprecation by our cloud infrastructure partner, Amazon Web Services (AWS), our team is actively transitioning the AI Essay Grading engine to the latest, next-generation Large Language Model (LLM). To guarantee the absolute precision, consistency, and fairness you expect from Brillium, our engineering teams will spend the next few days conducting rigorous regression testing and quality assurance on this new model. How This Affects You To prevent any disruption to your active testing programs, we are implementing a temporary operational adjustment: Automated Transition to Manual Grading: Effective immediately, all assessments currently configured for AI Essay Grading will automatically route essay results to Manual Grading. No Lost Data: Rest assured, all candidate submissions, responses, and core assessment data remain entirely secure and unaffected. Action Required: Administrators and evaluators will simply need to manually review and score essay responses within the Brillium platform during this brief interim period. Next Steps and Resolution We expect to seamlessly deploy the updated, high-performance AI Grading engine this coming Monday. Once deployed, the system will automatically resume automated grading for all designated assessments. We understand how vital these automated insights are to your workflows and sincerely appreciate your patience and partnership as we upgrade our infrastructure to better serve you.

What Has Been Completed? Our engineering team has successfully transitioned the AI Essay Grading engine to a next-generation Large Language Model (LLM). This upgrade has undergone regression testing and quality assurance to ensure precision, consistency, and fairness across all grading scenarios. Current System Status - Assessment Builder AI Essay Grading Fully Restored: All assessments configured for AI Essay Grading have resumed normal automated scoring functionality. - Manual Grading No Longer Required: Temporary routing to manual grading has been discontinued. - Data Integrity Confirmed: All candidate submissions, responses, and assessment data remain secure, complete, and unaffected throughout the transition. No further action is required. The enhanced model delivers improved reliability and performance aligned with our ongoing platform advancements. These enhancements ensure Brillium continues to deliver secure, high-performance, and future-ready assessment capabilities.

We are continuing to work on a fix for this issue.

This incident has been resolved.

**Executive Summary** Brillium recently experienced a temporary service disruption affecting the AI Essay Grading capability within Assessment Builder. This disruption occurred during a required upgrade to our underlying AI model after the previous model was deprecated by our cloud provider. The issue has been fully resolved, services have been restored, and there was no impact to customer data. We take full responsibility for the disruption and have implemented additional safeguards to strengthen our change management and service reliability processes. ‌ **Impact Overview** * **Service Affected:** AI Essay Grading \(Assessment Builder\) * **Customer Impact:** Temporary unavailability of automated grading * **Workaround Provided:** Temporary routing to manual grading * **Data Integrity:** No loss, corruption, or unauthorized access to customer data All candidate submissions and assessment results remained secure, complete, and unchanged throughout the incident. ‌ **Root Cause** The disruption was the result of an external dependency change. The Large Language Model \(LLM\) previously used by Brillium for AI Essay Grading was deprecated by AWS, requiring an accelerated transition to a supported next-generation model. During this transition: * Automated grading was temporarily paused to ensure a controlled and secure upgrade * Additional validation was required to confirm grading accuracy, consistency, and fairness * Safeguards were applied to protect processing integrity and prevent inaccurate scoring While this action was necessary to maintain platform stability and vendor support compliance, it introduced a temporary service interruption while validation and stabilization were completed. ‌ **Resolution** Our engineering team has successfully: * Transitioned the AI Essay Grading engine to a supported next-generation LLM * Completed comprehensive regression testing and quality assurance * Validated grading precision, consistency, and fairness across all scenarios * Fully restored automated scoring for all assessments Manual grading processes introduced during the incident have now been discontinued. ‌ **Current Status** * AI Essay Grading is fully operational * All assessments are processing normally * No further action is required ‌ **What We Are Doing to Prevent Recurrence** We are strengthening our platform and processes to reduce the likelihood and impact of similar events: * **Enhanced Third-Party Dependency Monitoring** Improved tracking of vendor lifecycle changes, including deprecations and end-of-support timelines * **Proactive Upgrade Planning** Earlier adoption cycles to reduce the need for accelerated transitions * **Expanded Pre-Deployment Testing** Increased simulation of production scenarios prior to release ‌ **Customer Assurance** We recognize how critical reliable scoring is to your operations. This upgrade ensures: * Improved grading accuracy and consistency * Greater long-term system stability and vendor alignment * Continued protection of all customer data Brillium remains committed to delivering secure, high-performance, and future-ready assessment solutions. ‌ **Support** If you have any questions or need assistance, our support team is here to help.
