A widespread outage of ChatGPT disrupted services for thousands of users globally on April 20, 2026, and OpenAI confirmed it was actively monitoring recovery efforts after deploying fixes.
Reports of the disruption began surfacing around mid-morning U.S. time, as users encountered issues ranging from failed logins to an inability to load conversations or generate responses. Outage tracking platforms recorded a sharp spike in complaints across multiple regions, reflecting the scale of the disruption.
OpenAI acknowledged the incident in its official status updates, stating that it was investigating a “partial outage” affecting ChatGPT and related services. The company said some users were “unable to access ChatGPT, Codex and API Platform,” confirming the issue’s breadth.
As mitigation efforts were implemented, OpenAI indicated that services were gradually stabilising. “We have applied the mitigation and are monitoring the recovery,” the company said in an update, signalling that systems were coming back online.
The outage was not uniform across all users. While some experienced complete service unavailability, others reported degraded performance, including slow responses and missing chat histories.
The disruption also extended beyond ChatGPT to other tools within OpenAI’s ecosystem, including its developer-focused offerings, suggesting a broader infrastructure-related problem.
Although services began to recover within hours, the incident underscores the growing dependence on AI-powered platforms for work and daily tasks, as users across sectors reported interruptions during the downtime. OpenAI has not disclosed the root cause of the outage as of press time.
