DeepSeek’s chatbot suffered a major outage of more than seven hours overnight in China on March 30, 2026, according to Bloomberg. The company was forced to deploy several sequential updates to restore service, marking the longest disruption since the AI startup’s public debut.
Users reported failed responses, timeout messages, and complete inability to access the chatbot during the outage. The need for multiple fixes suggests cascading failures rather than a single point of failure, though DeepSeek has not publicly disclosed the root cause.
The outage comes at a sensitive time for DeepSeek, which has rapidly become one of China’s most prominent AI platforms. The company attracted global attention in early 2026 with its DeepSeek-V3 model, which demonstrated competitive performance with significantly lower training costs than Western alternatives. The platform has since attracted millions of users across China.
For enterprise customers evaluating DeepSeek as an alternative to OpenAI or Anthropic, uptime reliability is a critical evaluation criterion. A seven-hour outage exceeds the downtime thresholds specified in most enterprise service level agreements, which typically guarantee 99.9% uptime or roughly 8.7 hours of total annual downtime.
