On May 27, 2026 Beijing Time, OpenAI confirmed that high latency issues had occurred with ChatGPT and API services, with users reporting significantly slower response times and extended waiting periods for replies. OpenAI officially acknowledged the issue on its status page at 22:47 on the same day and announced the completion of repairs at 4:06 AM on May 28, with services now restored to normal.
