service alert
System status notification
A service alert is a notice warning of disruptions or changes to a system—typically public transit, utilities, or online platforms.
Transit agencies issue service alerts for delays, route changes, or station closures: Check for service alerts before your commute.
The term implies temporary conditions rather than permanent schedule changes.
