  4. postmortem Jan 20, 2026, 05:24 PM UTC

    On Monday, December 22, 2025, from approximately 16:12 to 16:50 \(UTC\), some customers experienced errors when attempting to log in and log out across the KSAT console. This issue was caused by a cryptography library update required for a new feature. To resolve this issue, we reverted the update, and the KSAT console returned to normal performance by 16:50 \(UTC\). To prevent this type of issue in the future, we have updated our deployment workflows to require sanitation tests before new deployments are sent. No data loss occurred as a result of this issue.
