   ### Summary On March 3, an internal monitoring metric stopped being reported for approximately 14 hours. No customer metrics delivery was affected, all integrations continued operating normally. The missing metric caused our dashboards to display false failure rates, which was incorrectly reported as a metrics delivery outage. ### Impact None. Metrics continued to be delivered to all customer endpoints throughout the incident. ### Resolution The monitoring metric was restored and we have updated our alerting queries to be resilient to missing data, preventing false positives in the future.
