OpenAI confirmed that ChatGPT experienced a major outage, preventing users from accessing the platform along with related services including Codex and its API. The disruption began Monday morning and quickly escalated, with thousands of users reporting issues across multiple regions.
According to outage tracking site Downdetector, reports surged throughout the morning, surpassing 5,000 incidents within hours. Many users said they were unable to load ChatGPT entirely, while others experienced failures when attempting to use developer tools or APIs.
OpenAI’s status page acknowledged the issue, stating that users were unable to access core services and that the company was actively investigating. At the time of the latest update, no clear cause had been identified and services had not been fully restored.
Widespread Impact Across AI Services
The outage affected not only ChatGPT but also OpenAI’s broader ecosystem, including its API platform used by developers and businesses. This suggests the issue may be tied to underlying infrastructure rather than a single application.
The disruption highlights how dependent many users and organizations have become on AI services for daily workflows. From coding assistance to customer support and content generation, outages can have immediate operational impacts.
The number of reported issues continued to climb throughout the morning, indicating the problem persisted for several hours. OpenAI has not yet provided a timeline for full resolution or details on what caused the disruption.
