DeepSeek service suffers major outage, still not fully repaired after about 12 hours

DeepSeek (DeepSeek) experienced a major disruption to its web and mobile app services and, reportedly, the incident remains unresolved roughly 12 hours after it began. It has been reported that the company's official service-status page showed an initial service anomaly detected at 21:35 yesterday, which the team said was “resolved” at 23:23, only for new performance issues to be logged at 00:20. A repair was implemented at 01:24, but the service status page indicated the problem had not been fully fixed as of publication.

Timeline and scope

According to the incident report published on the status site, the first problem affected both the DeepSeek web portal and its mobile apps. The hands-on timeline is short but persistent: detection at 21:35, a first resolution notice at 23:23, fresh performance investigations from 00:20 and a repair attempt at 01:24 — yet users continued to report degraded access. It has been reported that outages were visible to end users rather than confined to internal monitoring.

What we know and what we don’t

DeepSeek has not publicly detailed the root cause. Was it an internal configuration error, third‑party infrastructure failure, or something else? That remains unclear. Reportedly, the company’s engineers are still working on a full restoration; no public post‑mortem or timeline for complete recovery had been posted at the time of reporting.

Context for Western readers

Outages at mid‑sized Chinese internet services can have outsized user impact because many platforms serve large domestic audiences via integrated web and app ecosystems. While there is no indication this incident is related to international sanctions or trade policy, China’s tightly regulated internet environment and reliance on domestic cloud and CDN providers can shape both failure modes and response practices. Users and enterprises reliant on DeepSeek’s services are advised to monitor the official status page and vendor communications for updates.
