DeepSeek goes down: chat and API offline for an hour

The AI lab's status page confirms an ongoing outage hitting Chat and two API services, with the cause identified and a fix in progress.

DeepSeek's chat service and API went down on October 14, with both the web app and the mobile app showing “server temporarily unavailable” messages. The company's official status page confirmed the disruption, stating the cause had been identified and a fix was being implemented, with the incident marked as ongoing for about an hour.

The outage affects three components: the Chat service, the DeepSeek V4 Pro API, and the DeepSeek V4.1 Flash API. Third-party outage trackers logged a sharp spike in user reports — nearly 180 in a single hour — indicating the disruption is widespread rather than regional. No estimated recovery time has been announced.

The timing underscores how central DeepSeek's models have become to the global AI stack. Since its open-weights models became the default choice for developers worldwide, even a brief outage ripples across countless applications built on its API.
