7. investigating Mar 12, 2026, 04:46 AM UTC

   We have confirmed that the recent increase in Code Function errors did not impact overall data flow. We identified an issue with recursive Code Function executions temporarily blocking throughput for a small number of customers. We have worked directly with the affected users to mitigate and stabilize their pipelines, and systems are operating as expected at this time and we are contiuing to monitor all signals.
