OpenAI’s popular AI chatbot ChatGPT faced a significant global outage on Tuesday, leaving millions of users unable to access the service. The disruption was first reported in the early hours of June 11, 2025, with users across North America, Europe, and Asia facing login issues, response delays, and complete service unavailability.
India and U.S. Users Report Maximum Disruption
India and the United States appeared to bear the brunt of the outage, as thousands of users turned to social media platforms like X (formerly Twitter) and Reddit to voice concerns. Downdetector, a website that monitors web service performance, recorded tens of thousands of complaints from users in both countries. Educational institutions, tech professionals, and content creators reliant on ChatGPT for work and productivity reported serious workflow disruptions.
OpenAI Responds With Swift Acknowledgement
OpenAI acknowledged the issue on its official status page, stating, “We are currently investigating a major outage affecting ChatGPT services. Our engineering team is working to resolve the issue as quickly as possible.” The company did not immediately disclose the root cause but assured users that updates would be provided promptly.
Outage Affects GPT-4, GPT-3.5 Models Across Web and API
The outage affected both free and premium users of ChatGPT, with reports confirming that even GPT-4 and GPT-3.5 models were unresponsive. Users trying to access ChatGPT via browser or API integration were met with error messages or unresponsive loading screens, suggesting a back-end infrastructure failure or overload.
Service Restored Gradually with Partial Functionality
By late evening (IST), OpenAI reported that services were being gradually restored. However, some users continued experiencing intermittent lags and limited access. The company has not confirmed whether the issue was due to a system update, cyberattack, or server failure, prompting speculation among experts.
Recurring Outages Raise Reliability Concerns
This is not the first time ChatGPT has experienced service disruptions. With AI tools becoming increasingly embedded in critical workflows, recurring outages are raising questions about the reliability and resilience of such platforms. Users and developers have called for greater transparency and more robust fallback systems in future updates.
