## Post-Incident Report – Dualog Service Disruption on 28 January 2026 **Incident Date:** 28 January 2026 **Duration:** 04:28 to 07:45 UTC **Affected Services:** Multiple services \(intermittent connectivity\) **Status:** Resolved ### Summary On 28 January 2026, our infrastructure experienced a network disruption that caused intermittent connectivity issues and reduced service availability between 04:28 and 07:45 UTC. All services were fully restored by 07:45 UTC, and no data was lost. ### Impact A network disruption occurred within our infrastructure, which temporarily impacted service availability during the time window noted above. * Services like Mail, Drive, Fetch, and the Dualog Portal experienced intermittent connectivity issues. * No data was lost. * All services were fully restored by 07:45 UTC. ### Root Cause A pre-existing internal network configuration issue, combined with an unexpected load spike on one of our servers, triggered a cascade effect that temporarily overwhelmed our network capacity. The incident also exposed a latent software bug that only manifested under these specific conditions. ### Resolution & Recovery Our team identified and removed the affected network component, then restored services using an improved configuration. Service stability was fully restored by 07:45 UTC. ### Preventive Measures We have implemented the following improvements to reduce the likelihood of recurrence: * Restructured internal network architecture for improved resilience. * Reduced the scope of shared network components to minimize cascade risk. * Requested increased capacity from our network provider. * Initiated a review of our infrastructure to standardize software versions. ### Data Integrity We have no indication of data loss, data leakage, or unauthorized access. ### Final Note At Dualog, service reliability is a top priority. We regret the inconvenience this disruption may have caused and appreciate your patience while we resolved the issue. We remain committed to strengthening the resilience of our platform and sharing transparent updates with our customers.

# Post-Incident Report – Dualog Service Interruption on 4 June 2025 **Incident Date:** 4 June 2025 **Duration:** 08:35 to 11:40 UTC **Affected Services:** Dualog Drive, Mail, and Portal **Status:** Resolved ## Summary On the morning of 4 June 2025, several Dualog services were disrupted due to an unplanned incident at our data center provider. The disruption impacted the availability of our customer portal, the performance of our email services, and the ability of Dualog Drive to send and receive files. While services were gradually restored within a few hours, a subset of Dualog Drive installations continued to experience issues with delayed or stuck file transfers beyond the initial downtime window. ## Timeline of Key Events ## Root Cause Our hosting partner was in the process of upgrading their infrastructure. During this activity, they performed a disk cleanup operation on shared storage systems. A misconfigured setting during this process introduced **unintended disk I/O throttling**, leading to service degradation and temporary failures. Additionally, within our own infrastructure, a Dualog Drive database setting prioritized availability over consistency. This contributed to residual synchronization issues even after services were restored. ## Impact * **Dualog Drive** was partially unavailable for approximately 90 minutes and experienced follow-up issues on some vessels due to corrupted sync states. In a few cases, this led to lost files, which had to be manually resent by the sender. * **Dualog Mail services** were intermittently unstable. * **The Dualog Portal** used for monitoring and configuration experienced degraded performance during most of the incident. * Other services remained unaffected. ## Resolution & Recovery * A fix was deployed at the infrastructure level by our provider to eliminate the I/O throttling configuration and improve cleanup testing procedures. * A new version of Dualog Drive was released to recover from corrupted sync states. This patch is now available and was applied to affected installations. * Support teams have actively worked with customers to resolve residual file transfers and update installations. Affected customers were contacted directly with relevant file details and guidance for recovery. ## Data Integrity We have no indication of data leakage or unauthorized access. ## Preventive Measures We are committed to ensuring this does not happen again. As part of our long-term mitigation: * We are updating internal database settings to prioritize consistency in all clustered deployments. * We are revising error handling in Dualog Drive to better manage unexpected states from backend systems. * Our provider has committed to stricter safeguards when performing maintenance on shared infrastructure. ## Final Note At Dualog, operational reliability is a cornerstone of our service, and we treat incidents like these with the utmost seriousness. We regret the inconvenience this incident may have caused and remain committed to providing a resilient and transparent service experience. We appreciate your patience and trust as we work to reinforce the resilience of our platform.
