On Sunday, 3/13/2022, from approximately 9:15 a.m until 5:50 p.m. (ET), users were unable to access their KMSAT console.
The incident was caused by high memory usage on a service that caches user logins. Once the memory usage was reduced, KMSAT was able to return to normal performance by 5:50 p.m. (ET).
We monitor for high memory usage as a standard practice, but a minor issue with our monitoring system delayed our awareness of this incident. We have fixed the issue and are adding additional monitoring and alerts to our workflow to prevent this in the future.
No data loss occurred as a result of this issue.
