OpenAI experienced a service disruption on Sunday, July 12, 2026, causing widespread access issues for ChatGPT users. The company officially acknowledged that some users on iOS devices are encountering 403 errors when attempting to load or interact with their conversations. This specific error typically indicates that a server understands a request but refuses to grant access, though the company has not yet confirmed the underlying cause of the failure. In addition to these access errors, OpenAI reported elevated conversation error rates for iPhone users, and the service remains partially unavailable as investigations continue.

Data from the outage tracking platform Downdetector indicates that more than 300 users in the United States reported problems during this window. User complaints were categorized as 77% related to general ChatGPT functionality, 15% linked to the mobile application, and 5% involving login failures. The impact has been particularly noted across several major cities, including New York, Houston, Chicago, Los Angeles, and San Francisco. Users have expressed frustration across social media platforms like X, with some reporting that these intermittent connectivity challenges have persisted over the past 2 weeks. OpenAI has stated it is actively investigating the situation and will provide further updates as the team restores full service.
