Overview
- DeepSeek’s website and app went down overnight in a major disruption that locked users out, cut off chats, and caused some content loss before service returned to normal.
- Company status updates described multiple repair steps through the night and a later notice that the fault was fixed, with teams continuing to watch system performance.
- The status page did not name a root cause and tagged the incident as a major web and app performance failure, while noting the company’s API stayed online.
- During partial recovery, people could log in but prompts only showed the assistant’s internal reasoning without delivering final answers until a later fix restored normal replies.
- Users had reported sharper web results and a new self‑description as “DeepSeek‑V3” before the outage, leading observers to speculate about a silent upgrade or a coming V4 that the company has not confirmed.
