### **Summary of Impact** On the morning of April 13, 2026, users of [adbook02.fattail.com](http://adbook02.fattail.com) experienced slow performance and difficulty accessing the system. This included issues logging in, running reports, and navigating between pages. Performance degradation was first observed and reported at approx. 5.30am EST. The FatTail engineering team was able to resolve and restore services at approximately 10.25am EST. ### **Root Cause** The slowdown was caused by degradation of one of the reporting services under a period of elevated request volume. The service continued accepting requests but was unable to process them efficiently which impacted overall system performance. Once the affected service was restarted, the backlog cleared and performance returned to normal. **Mitigation and Next Steps** To prevent recurrence, the FatTail team is implementing the following improvements: 1. Improve system protection and traffic management Adjust service throttling and implement additional safeguards to better control concurrent requests and prevent overload during traffic spikes. 1. Strengthen monitoring, alerting, and traffic analysis Enhance monitoring and alerting to detect and address sources of unusually high traffic. Additionally FatTail Support will provide more frequent ticket communication to affected clients while incidents are active.
