Zus Health incident
[Resolved] Some patients were unavailable in the Zus Web Application
Resolved after 1 hour, affecting Applications and Zus App, on May 4, 2026.
From 3:48pm ET - 4:45pm ET some patients were not accessible in the Zus Web Application. Navigating to the patient ZAP would have resulted in a message that the patient was “inactive” when they were in fact “active.” We identified the root cause and are deploying additional protections to ensure this will not happen again.
