ChatGPT experienced a significant outage on March 24, 2025, affecting thousands of users in the US and UK. The service was reported to be down by multiple users, with some expressing frustration on social media platforms. The outage was confirmed by reports from DownDetector, indicating widespread issues with both ChatGPT and the Sora app from OpenAI. The service was restored later in the day, with users confirming that ChatGPT was back online. In other tech news, OpenAI is reportedly gathering feedback for an updated version of GPT-4.5, following a leak last year about a model with a context window of 256K tokens. Additionally, there are rumors that the upcoming GPT-5 might not be available to Plus users initially due to its high cost.
