- postmortem Sep 04, 2026, 09:33 AM UTC
**Summary** On September 1st, Act-On customers hosted on **aorpci9** experienced login issues and degraded performance, resulting in an inability to access the platform. The issue was identified and resolved by approximately 7:00 AM PDT, with full access restored at that time. **Root cause** The incident was caused by a significant spike in traffic combined with resource contention within the application, which caused active processing threads to build up rapidly and overwhelm the affected environment. This resulted in the platform becoming slow or unresponsive for affected users until service was restored. We have identified the contributing factors and are taking steps to reduce the likelihood of recurrence. **What we are doing about it** * We are reviewing the traffic and resource conditions that led to the spike to better understand and mitigate similar patterns in the future. * We are reviewing our internal monitoring configuration to ensure incidents of this nature are detected and escalated more rapidly. * We are assessing configuration changes to reduce the likelihood and impact of similar conditions occurring in the future.
