Is ChatGPT down? Users in various regions around the world reported access failures to ChatGPT, the artificial intelligence tool developed by OpenAI, around 12:41 this Monday, October 27, 2025. The interruption, which mainly affected text queries and response generation, occurred globally, with peaks in complaints on monitoring platforms like Downdetector. OpenAI, the company headquartered in the United States, began investigations to identify the cause of the issue, which appears linked to server overload.
Initial reports indicate the outage lasted about 30 minutes in some cases, with users receiving error messages such as “network unavailable” or incomplete responses. The incident happened during peak usage hours, impacting professionals who rely on the tool for daily tasks.
- Main complaints include slow responses (reported by 83% of affected users).
- Errors on the official website accounted for 10% of incidents.
- Issues with the mobile app totaled 7% of notifications.
This data emerged from real-time monitoring, highlighting the growing reliance on AI in professional and personal routines.
User reports multiplied quickly after 12:30, with notification peaks at 12:41. The tool, launched in 2022, records billions of monthly interactions, amplifying the impact of brief failures.

Immediate measures taken
OpenAI’s support team redirected traffic to secondary servers in less than 15 minutes. This action restored access for 70% of affected users by 1:00 PM.
Internal reports indicate load tests were intensified to prevent recurrences. The company monitors the system 24 hours a day.
- Traffic redirection avoided total collapse.
- Notifications were sent via email to premium accounts.
- Manual checks confirmed partial resolution.
These steps follow protocols established from previous incidents.
