# Model status

What the four model states mean, the uptime thresholds, the time ranges and what is not counted.

The Status page shows the state of each model and its uptime. Uptime is counted **per request**: one request counts once, even if sivcloud tries several channels behind it.

## The four states

| State | Meaning |
|---|---|
| Operational | Uptime of 99% or more |
| Degraded | Uptime from 50% up to below 99% |
| Down | Uptime below 50%: most requests fail |
| No data | Fewer than 10 counted requests |

The current state is computed from the last 30 minutes. With fewer than 10 requests, the last 24 hours are used.

## Time ranges

The uptime chart can be viewed per 24 hours, 7 days, 30 days or 90 days.

## What is not counted

Status measures the service, not the caller's mistakes. These do not lower uptime:

- A channel attempt that failed but was retried and then succeeded.
- A stream cut off by the client.
- Upstream errors caused by the request content: status 400, 404, 413, 422, and the codes `content_policy_violation`, `content_filter`, `context_length_exceeded`.
- Requests rejected before being forwarded: invalid key, empty balance or rate limit. See [Error codes](https://sivcloud.com/en/docs/errors/).
