How long was DeepSeek chatbot outage?

DeepSeek chatbot hit a major outage in China

DeepSeek’s chatbot suffered a major outage lasting over seven hours in China, described as its biggest disruption since the system debuted in 2025. The downtime was unusual for a chatbot that is widely used globally, highlighting how even highly visible AI services can experience prolonged reliability issues.

The outage matters for two reasons.

First, it points to operational fragility under real-world demand. Chatbots are interactive systems with heavy reliance on compute capacity and upstream dependencies; when a service goes down for hours, it can affect users’ ability to complete routine tasks and can disrupt integrations in workflows.

Second, the incident provides a reminder that “AI everywhere” doesn’t automatically mean “always available.” As chatbots become embedded in consumer apps and enterprise tooling, availability expectations typically rise, so outages can become reputationally and commercially costly.

The report doesn’t include further technical specifics—such as the root cause, whether it was tied to a model, infrastructure, or traffic surge—and no mitigation details were provided in the available summary. What’s clear from the headline facts is the scope (China-focused), the duration (more than seven hours), and that it is the company’s largest outage since launch.

For users, the immediate impact was simple: the chatbot was unavailable during that window. For industry watchers, the longer-term signal is that reliability incidents remain an important metric as AI products move from demos to dependable services.
