- postmortem Sep 23, 2025, 05:25 PM UTC
Our investigation revealed that at approxiamately 2025-09-23T12:29:10Z \(UTC\) we experienced a temporary service disruption caused by an unexpected and extreme surge in network traffic. At peak, our systems were servicing over 20,000 simultaneous requests per second, which impacted Application Builder performance for a significant segment of our customers. Initial analysis of our Application Firewall \(AF\) logs shows that requests were valid and there is no indication of malicious activity. Our System Operations team reviewed and refreshed affected systems to restore system services performance and availability. We will continue to investigate the root cause data and apply additional operational enhancements aimed at improving the platform’s ability to handle unusual activity of this nature.
