ChatGPT was down for many on Monday (March 24), especially users in the US, where prompts were returning error messages across multiple models, including 4o and 03-mini.
We first noticed the issue on a number of our own ChatGPT queries and then confirmed that others are reporting similar issues with the artificial intelligence platform on Downdetector and on Reddit. Dwondetector, which tracks outages across the web, noted outage reports starting at roughly 9AM ET and growing since then until then started declining around 11AM ET.
