ChatGPT is experiencing a widespread outage, leaving thousands of users unable to access the platform. OpenAI has confirmed it is investigating the problem, which is also affecting Codex, its AI-powered coding tool.
Reports of issues began surfacing at around 10:05am ET on Monday, April 20, 2026. Outage tracking site, Downdetector, recorded a sudden surge in complaints shortly after.
At the time of writing, more than 7,600 users in the United Kingdom (U.K.) and 1,700 users in the United States (U.S.) had flagged problems.
According to OpenAI, a total of 12 components of ChatGPT and one component of Codex was affected in the outage.
The outage appears to be over as OpenAI shared an update acknowledging the disruption, saying, “Users unable to load ChatGPT, Codex and API platforms.”
The San-Fracisco based company said that it had applied the mitigation and the team was monitoring the recovery.
Rough estimates suggest that the chatbot gets around 200 million active users everyday.
