DeepSeek goes down for seven hours in biggest outage since debut

DeepSeek’s chatbot suffered a major outage of more than seven hours overnight in China, forcing the AI pioneer to deploy several updates to rectify the issue.

Users began reporting faults on Sunday evening, according to Downdetector. The startup’s own status page acknowledged an initial issue at 9:35 p.m. before marking the incident resolved two hours later. Subsequent updates on Monday showed DeepSeek addressing another case of performance issues that took until 10:33 a.m. to be fixed.

The causes of the outages remain unclear and DeepSeek did not immediately respond to an emailed request for comment.
