Disruptions, also known as service updates, are used by operators to let users know when there is a problem on their network.
Disruptions are distinct from real-time updates to stop visit times or vehicle locations. Disruptions are also distinct from journey cancellations - though a real-world disruption may cause a cancellation.
In Passenger Cloud, there are 3 main types of service updates that are available to operators:
Both current and future alerts are shown so customers can see disruptions that affect current and future journeys.
On timetable pages, only alerts that apply to the current date/time selection are shown. Disruptions that are restricted to a start/end time, rather than a full-day disruption, will only show when that time period is current.
