Overview
- DeepSeek suffered a partial outage that disrupted its web chat and its V4 Pro and V4.1 Flash APIs from 08:11 to 13:04 Beijing time on Thursday, October 15, 2026.
- Users reported slow or no replies, loading hangs and ‘server busy’ or ‘too many requests’ errors while third‑party monitors logged dozens of related alerts.
- DeepSeek restored services after roughly five hours and said it will automatically credit each API account with the amount they consumed during Oct. 8–Oct. 14.
- The company said it has begun a comprehensive stability review and plans to remove single‑point dependencies to reduce the risk of repeat outages.
- A new Bilibili account named “DeepSeekHarness” surfaced at the same time and prompted speculation about a product link, but DeepSeek has not provided evidence tying the account to the outage.
