Timeline of updates
- investigating
We are investigating an issue where Metric Alerts are triggering at thresholds that do not match the underlying metric data for customers in both our EU and NA data centers. Customers may be receiving alert notifications that appear to fire incorrectly or more frequently than expected.
Our engineering team has been notified and is actively investigating. We will provide an update as soon as we have more information.
We apologize for the disruption and appreciate your patience.
- resolved
As of 9:36 AM ET on June 11, 2026, this issue is resolved. A feature flag introduced as part of our multi-metric support rollout caused alert evaluations to diverge from actual metric values, resulting in Metric Alerts firing incorrectly even when the underlying metric had not breached its threshold.
Start time of this issue:
Multi-Metric Beta customers: June 4, 2026 at 10:27 AM ET
All other customers using Metrics with division: June 10, 2026 at 4:25 PM ETIf you continue to receive alerts you believe are incorrect, please reach out to us at support@fullstory.com. We apologize for the disruption.
