Chatgpt had a fairly clear end until 2023. There were only a few short and partial breakdowns in the months of September and October, followed by a reasonably level breakdown in November which put the cat- Offline line for a while.
The most recent major breakdown took place in May 2024, which altered the capacity of Chatgpt to access the Internet and meant that users could not access the complete chatbot capabilities for more than eight hours. It was the first big breakdown since April 2024, which was not as severe and only lasted three hours.
