OpenAI Outage Postmortem: Telemetry Service Disrupts AI Platforms
OpenAI experienced a significant outage affecting ChatGPT, Sora, and its API on Wednesday. The disruption, lasting roughly three hours, stemmed from a newly deployed telemetry service designed to collect Kubernetes metrics. This service unintentionally triggered resource-intensive operations, overwhelming the Kubernetes API servers and causing widespread issues.
Technical Breakdown
The telemetry service's configuration inadvertently led to excessive Kubernetes API operations, impacting the system's control plane. This disruption affected DNS resolution, a crucial process that converts IP addresses to domain names. OpenAI's use of DNS caching further complicated the situation by delaying the identification of the problem's full extent. See more about how to fix Wi-Fi issues.
Impact and Resolution
While OpenAI detected the issue shortly before customer impact, the overwhelmed Kubernetes servers hindered swift remediation. The incident highlighted a confluence of system and process failures, including inadequate testing and slow remediation processes.

Preventive Measures
OpenAI has outlined steps to prevent future incidents, including enhanced monitoring for infrastructure changes, improved phased rollouts, and new access mechanisms for engineers to Kubernetes API servers. These measures aim to bolster system resilience and minimize disruptions. Learn more about fixing SOS Mode on iOS 18.2.
Apology and Commitment
OpenAI acknowledged the disruption's impact on users, developers, and businesses, expressing regret for falling short of expectations. The company emphasized its commitment to improving system reliability and preventing similar outages.
