## Updates

### + Resolved — Sep 15, 7:27 PM

affects: App (operational), API (operational)

Performance metrics have returned to baseline, and booking flows, calendar syncs, and user dashboards are fully functional. Thank you for your patience and understanding while we resolved this issue!

### x Monitoring — Sep 15, 7:08 PM

affects: App (operational), API (operational)

We have identified the root cause of the ongoing performance degradation affecting Cal.com. An high-volume query began flooding our system starting at 18:00 UTC, leading to resource contention and slower response times.

Our engineering team has successfully reverted the change that introduced the query. We are now observing system metrics stabilize as services recover. Core scheduling and booking flows should progressively return to normal.

We will continue to monitor closely and provide a final resolution update shortly.

### x Identified — Sep 15, 6:30 PM

We are currently investigating reports of degraded performance affecting the Cal.com web application
