- postmortem May 14, 2026, 04:26 PM UTC
On May 12, 2026, our platform experienced a processing delay affecting journal transfers. The issue originated from an unexpected surge in volume. However, no transactions were lost, rejected, or duplicated and there was no impact to funds or positions. 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..
