ChatGPT Down On July 16, 2025, many users around the world couldn’t access ChatGPT. People saw errors like “unusual activity detected” or were blocked from using chat features and their history. More than 3,400 users in the U.S. alone reported problems, according to Downdetector.
This issue wasn’t limited to just ChatGPT. Other OpenAI services like Sora and CodeX were also affected. Is there any positive news? OpenAI quickly identified the cause and began fixing it the same day.

The problem was tied to high error rates across OpenAI tools. While the exact reason wasn’t fully shared, technical experts believe it could have been due to too many requests at once, system overload, or security filters wrongly flagging users.
