Log ingestion disruption for Line agent calls

Incident Report for Cartesia AI

Resolved

Duration: March 10, 2026, 9:00 AM PST - 9:14 PM PST

Impact: Runtime logs for Line agent calls made during this time period were not available via the dashboard or API. Call processing was not affected.

Resolution: Our engineering team identified the root cause as an upstream breaking change from an infrastructure provider that disrupted our log ingestion pipeline. A hotfix was deployed and log collection has been fully restored. All logs from the affected window have also now been recovered and backfilled.

Next Steps: We are conducting a postmortem to improve reliability and detection speed moving forward.
