# Uptime Issues

An uptime issue is a grouping of detected downtime events for a specific URL. A downtime event is generated by active uptime alerts when HTTP requests fail to meet our [uptime check criteria](https://docs.sentry.io/product/uptime-monitoring.md#uptime-check-criteria).

## [Traced Errors](https://docs.sentry.io/product/issues/issue-details/uptime-issues.md#traced-errors)

Uptime checks made against web services configured with one of Sentry's supported SDKs contain a [trace](https://docs.sentry.io/concepts/key-terms/tracing.md) that can be used to track detected errors resulting from failed HTTP uptime checks. The trace navigator allows you to browse through potential root causes of your downtime and is a powerful tool for quickly identifying and resolving issues.

## [Issue Lifecycle](https://docs.sentry.io/product/issues/issue-details/uptime-issues.md#issue-lifecycle)

Uptime issues are grouped by the monitored URL and created upon the first detected downtime. Sentry automatically resolves an ongoing uptime issue when the monitored URL returns to a healthy status and meets our [uptime check criteria](https://docs.sentry.io/product/uptime-monitoring.md#uptime-check-criteria). If the URL experiences subsequent downtime, the issue's status will change to regressed.
