Background & analysis
On November 3, DeepSeek suffered another large-scale service outage in the afternoon. From 16:58 onward, DeepSeek's official status page confirmed a partial service interruption affecting the Chat Service, the DeepSeek V4 Pro API, and the DeepSeek V4.1 Flash API. Users attempting to use the chat function were shown a "Server busy, please try again later" message, and the hashtag #DeepSeek崩了# quickly rose to the top of social media trending lists.
DeepSeek later updated that it had implemented fixes for the web and API disruptions and moved into a monitoring phase. As of the latest status update, however, the API services for V4 Pro and V4.1 Flash as well as the Chat Service were still experiencing performance degradation and had not fully recovered. According to Wall Street CN's tally, this marks at least the 19th major service anomaly for the platform so far this year. The outage hit both everyday users and developers: the web interface and the mobile app could not respond to messages, while enterprises and developers integrating the DeepSeek V4 Pro API and V4.1 Flash API into their own products were unable to call the interfaces normally.

Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
