Journal Processing Delays — June 1, 2026

Incident Report for Alpaca

Postmortem

On June 1, 2026, our platform experienced a processing delay affecting journal cash transfers (JNLCs). The issue originated from a surge in journal volume at market open, which caused unexpected delays. However, no transactions were lost, rejected, or duplicated, and there was no impact to funds or positions. All queued journals were processed in order once throughput was restored.

Our engineering teams deployed a fix and continued to monitor the situation for 24 hours post deployment. There have been no issues since and the incident is now closed.

We know timely processing is critical to your operations, and we thank you for your understanding as we restored services.
