Was the SambaNova API down on September 11, 2026?
Not attributably. 1 multi-region failure(s) of SambaNova coincided with failures of other providers, so the cause sat above SambaNova and is not blamed on it. SambaNova’s status page lists nothing that day.
| UTC | What failed | Regions | Duration | Failed probes | Verdict | Error |
|---|---|---|---|---|---|---|
| 01:48–01:53 | host probes | 2 of 4: Europe (Germany), South America (São Paulo) | ≥5 min | 3 | shared with 1 other provider(s) — not attributed | timeout |

51 single-region failure(s) were also recorded that day (yi-01ai 23, google 16, iflytek 3, doubao 3, sambanova 2, perplexity 2, baichuan 1, writer 1). A failure seen from one region cannot be separated from a problem on that network path, so none of them is called an outage.
How is an outage told apart from a network problem?
Each provider is probed every five minutes from 4 independent regions. A failure is attributed to the provider only when it is seen from two or more regions at once and no other provider fails in the same minutes; a failure shared with other providers has a cause above all of them and is not blamed on anyone. Durations are lower bounds: we see the first and last failed probe, not the real start and end. Status-page entries are the provider’s own words, shown next to the measurement, not instead of it.
