# **Incident Summary** On June 12, 2026, Mindtickle experienced a service disruption caused by an unexpected surge in processing activity within one of our backend workflows. The resulting increase in downstream traffic exceeded the capacity of a critical platform dependency, leading to service degradation and eventual unavailability. The issue was mitigated by reducing processing throughput and allowing affected systems to recover. **Impact Duration:** **3 hours and 15 minutes**. ## **Impact** During the incident window, customers may have experienced: * Delays in invitation-related workflows * Elevated latency and intermittent errors across affected services * Temporary degradation of platform functionality dependent on the impacted backend systems ## **Incident Timeline** * ‌**Jun 12, 03:00 PM**: A critical backend dependency becomes saturated, resulting in service degradation and elevated error rates. * **Jun 12, 03:15 PM**: The issue is detected through automated monitoring and customer reports. Investigation begins. * **Jun 12, 04:50 PM**: Mitigation measures are implemented to reduce processing throughput and stabilize affected systems. * **Jun 12, 05:46 PM**: Platform functionality is restored fully ## **Root Cause** A backend workflow generated a significantly higher volume of processing activity than historical norms. As the system worked through the resulting backlog, requests propagated through multiple downstream services, creating sustained load across the platform. While each component behaved as designed, the combined volume exposed capacity and protection gaps within the processing chain. The resulting amplification effect overwhelmed a critical backend dependency, causing service degradation and eventual unavailability. ## **Resolution** The team mitigated the incident by reducing the rate at which backlog processing occurred, allowing downstream systems to stabilize and recover. Once traffic levels returned to normal operating ranges, affected services resumed normal operation and platform functionality was fully restored. ## **Corrective and Preventive Actions** * Introduce rate limiting and additional safeguards for high-volume processing workflows to prevent a single workflow from generating excessive downstream load. * Implement backpressure, circuit-breaking, and load-shedding mechanisms across critical processing paths to better protect downstream dependencies during traffic spikes. * Review platform capacity limits, concurrency settings, and monitoring to improve resilience and provide earlier visibility into abnormal processing patterns.

On July 28, 2025, the Call Recording service experienced an outage due to failures in Call AI's bot deployment infrastructure

### **Incident Summary** On July 28, 2025, the Call Recording service experienced an outage due to failures in Call AI's bot deployment infrastructure. During the incident, Call AI bots, which are responsible for joining and recording meetings, failed to launch, resulting in the inability to capture both scheduled and ad-hoc calls. * **Duration of Impact:** 4 hours 40 minutes \(01:48 AM to 06:28 AM PT\) #### **Impact Area:** * Call AI bots did not join meetings at the start time or on-demand **Root Cause Analysis** The outage occurred due to a failure in Call AI's bot deployment process triggered by **rate limiting from AWS Elastic Container Registry \(ECR\)**. * A sudden spike in bot launch requests crossed AWS ECR's per-second API rate limits. * The existing retry mechanism was not fully optimized, which resulted in a high volume of repeated requests and contributed to increased rate limiting. * The bot deployment system became locked in a loop, unable to fetch required container images, causing new bots to consistently fail to launch. Additionally, metrics for AWS ECR usage were being collected at a lower granularity, delaying the early detection of rate limiting issues. **Detection and Resolution Timeline \(Pacific Time\)** **Remediation and Preventive Actions** 1. **Retry Logic Improvements:** Enhanced the retry strategy with exponential backoff and circuit breaking to avoid future retry storms. 2. **Monitoring Enhancements:** Increased metric granularity and added real-time alerts for AWS ECR rate limits. 3. **Deployment Optimization:** Introduced caching and throttling at the deployment layer to better handle sudden surges in bot requests. We sincerely apologize for the disruption this incident caused and remain committed to delivering a reliable and resilient service to our customers.

On June 5th, 2025, between 1:36 AM PT and 2:06 AM PT, users experienced an issue where the Series and Modules were inaccessible on the Mindtickle platform. The issue was resolved at 2:06 AM PT, and full access to both Series and Modules has been successfully restored. We are actively monitoring the system to ensure continued stability. A detailed Root Cause Analysis (RCA) will be shared shortly.

**Incident Summary** On June 5, 2025, a temporary issue was observed where users were unable to view the Series Listing Page across the platform. The root cause was traced to a misconfiguration in the infrastructure setup of a new caching service \(Amazon DAX\) introduced to improve system performance. The configuration error blocked communication between application services and the DAX cluster, leading to service disruptions. The issue was promptly identified and resolved by rolling back the change. **Impact Area** The following functionality was impacted during the incident: * Series Listing Page \(site-wide impact\) **Incident Timeline** * June 5, 2025, 1:37 AM PT: Users began experiencing issues with the Series Listing Page. * June 5, 2025, 1:56 AM PT: The engineering team detected the issue and initiated an investigation.June 5, 2025, 2:08 AM PT: Rollback completed and services were restored to a stable state. **Root Cause Analysis** The issue was caused by a misconfiguration in the security settings of the newly introduced Amazon DAX cluster in the production environment. The security group associated with the cluster did not allow required inbound traffic from the application services. This caused service pods to fail and led to errors on the Series Listing Page. **Next Steps and Preventive Actions** * **Improved Health Checks**: Applications will include readiness and liveness probes for external dependencies like DAX to detect failures earlier. * **Enhanced Monitoring and Alerts**: DAX metrics will be integrated into the monitoring framework to ensure real-time visibility and proactive alerts. We apologize for the inconvenience caused by this incident.
