Maintenance Events
Maintenance events indicate browser lifecycle issues such as unexpected closures, startup failures, and authentication errors.
Maintenance events appear under the Access category in the Events screen but represent system health and availability concerns rather than user-initiated access activity.
The authenticationFailure event is also included here because it typically indicates a system or configuration issue rather than a deliberate user action.
