ChatGPT is down on Monday April 20, 2026 — here’s what we know

If you opened ChatGPT on Monday morning, April 20, 2026, and ran into a loading error or blank screen, you’re not alone. OpenAI’s flagship AI chatbot is experiencing a widespread outage affecting users globally, with both ChatGPT and the developer-focused Codex platform confirmed as impacted.

OpenAI acknowledged the issue on its official status page, stating that users are unable to load ChatGPT and Codex, and that the company is actively investigating the cause. No estimated resolution time has been provided as of the time of writing.

What the outage looks like on the ground

Reports began flooding into outage-tracking platform Downdetector early Monday morning, with the site displaying a significant spike in user complaints, the kind of sharp red surge that typically signals a major, widespread service disruption rather than isolated technical hiccups.

User reports indicate problems with OpenAI since 10:39 AM EDT.

Users across social media platforms quickly confirmed the experience: attempts to load the ChatGPT web interface and mobile app are failing, with many seeing timeout errors or unresponsive screens. Codex, OpenAI’s code-generation tool used widely by software developers, is similarly offline.

Why this outage matters

ChatGPT has grown into a daily utility for hundreds of millions of people worldwide, used for everything from drafting emails and writing code to research, creative projects, and customer-facing business tools. A Monday morning outage hits particularly hard, as weekday working hours represent peak usage for both individual and enterprise users.

For developers relying on the OpenAI API to power their own applications and services, a Codex disruption adds a second layer of impact, potentially taking downstream products offline alongside the consumer-facing ChatGPT interface.

OpenAI has confirmed awareness of the issue via its status page, which lists both ChatGPT and Codex as affected services currently under investigation. The company has not yet disclosed the root cause or offered a timeline for recovery. This page, status.openai.com, remains the most reliable source for real-time updates directly from OpenAI during any service disruption.

What to do while ChatGPT is unavailable

While OpenAI works to restore service, users needing immediate AI assistance have several alternatives available, including Google Gemini, Anthropic’s Claude, and Microsoft Copilot, all of which remain operational. Developers affected by the Codex outage may wish to check whether their API calls can be temporarily rerouted to alternative model endpoints.
