DeepSeek experienced another major service outage on the afternoon of November 3, with both the web platform and API interfaces failing simultaneously—this marks at least the 19th significant disruption on the platform this year.

Starting at 16:58 on November 3, DeepSeek’s official status page confirmed a partial service outage, affecting the Chat Service, DeepSeek V4 Pro API, and DeepSeek V4.1 Flash API. Users attempting to use the chat feature received a message stating, “Server busy, please try again later.” The topic #DeepSeekDown immediately trended on social media.

DeepSeek later updated that repairs have been implemented for the website and API service outages, and the system is now under monitoring; however, as of the latest status update, the API and chat services for V4 Pro and V4.1 Flash still exhibit degraded performance and have not fully returned to normal.

Scope of the outage: Affects both regular users and developers

This outage affects both end users and developers. Among end users, both the web platform and mobile app are unable to respond to messages normally. Among developers, the DeepSeek V4 Pro API and V4.1 Flash API services have simultaneously failed, meaning businesses and developers integrating this model into their products cannot invoke the APIs normally, directly impacting downstream commercial applications that rely on this service.

On social platforms, users have reported affected scenarios including article editing, code writing, and thesis writing, among other common work tasks.

Analysts point out that the core issue behind frequent service outages is a severe imbalance between computing power supply and demand. As user numbers and API call volumes continue to grow, DeepSeek still faces significant pressure in terms of infrastructure capacity and stability assurance.

At least the 19th time this year: Frequent outages have occurred since October.

Statistics show that this is at least the 19th major anomaly by DeepSeek this year, and since October, the incidents have become increasingly frequent.

On October 2, web and API service disruptions lasted approximately two hours, affecting the V4 Pro API, V4.1 Flash API, and chat services; on October 8, the platform experienced a performance degradation lasting about three minutes; on October 12, DeepSeek encountered two separate outages within a single day, one of which simultaneously impacted both chat services and the V4.1 Flash API; on October 15, the platform suffered another major outage, with both the web interface and API endpoints failing simultaneously, and the issue remained unresolved after nearly three hours.
