At approximately 16:58 on November 3, DeepSeek's website and API experienced partial disruptions. The affected components included the DeepSeek V4.1 Flash API service, the chat service, and the DeepSeek V4 Pro API service. The platform has since implemented fixes and is monitoring the results, with all three components currently showing degraded performance. Previously, on October 15, DeepSeek had suffered a service failure lasting nearly five hours, and the incident became a trending topic on social media. Following that fix, the platform compensated users with bonus credits.
