At 07:18 AM EST, Imprivata received multiple alerts in our US Shared cluster related to message queue alerts which resulted in performance degradation and impacted deployments. This was caused by a service interruption at an external email vendor, which cascaded into GroundControl. At 07:43 AM EST, Imprivata began a staggered restart of the instances to remediate the issue and operation began to normalize. Customers may have continued to experience lingering issues in performance throughout the day. All services are back to pre-incident state as of January 31st.
