# Service Disruption on August 21 — What Happened On August 21, between 12:12 and 13:40 PDT, some customers experienced failed Chat and Agent requests. A routine software update exposed a dormant bug in how certain conversation histories were processed, causing roughly 12% of conversations to return errors; new conversations were largely unaffected. We rolled back the update within the hour and deployed a permanent fix the same day. Our internal review identified where our safeguards fell short, and our team is already putting in place a combination of agentic, programmatic, and human safeguards to ensure an issue like this cannot reach customers again. We're sorry for the disruption, and we thank the customers who reported the issue. Please reach out to your account contact or support if you have questions.
