HEAD request with a timeout of 5 seconds. If we detect a downtime, we perform subsequent tests every 10 minutes, until the resource is back online.For SIRI and SIRI Lite feeds, we perform a
GET request: a 401 or 405 status code is considered successful. In case of HTTP 500, the feed will be considered unavailable, unless the body appears to contain SOAP.Validation details

Sequential stop_time_update times are not increasing E022 168 errors
stop_time_update arrival/departure times between sequential stops should always increase - they should never be the same or decrease.
Sample errors
- trip_id 1-691666964 stop_sequence 22 arrival_time 08:10:20 (1769497820) is equal to previous stop arrival_time 08:10:20 (1769497820) - times must increase between two sequential stops
- trip_id 1-691666964 stop_sequence 22 arrival_time 08:10:20 (1769497820) is equal to previous stop departure_time 08:10:20 (1769497820) - times must increase between two sequential stops
- trip_id 1-691666964 stop_sequence 22 departure_time 08:10:20 (1769497820) is equal to previous stop departure_time 08:10:20 (1769497820) - times must increase between two sequential stops
- trip_id 1-691666964 stop_sequence 22 departure_time 08:10:20 (1769497820) is equal to previous stop arrival_time 08:10:20 (1769497820) - times must increase between two sequential stops
- trip_id 1-691470340 stop_sequence 12 arrival_time 08:09:25 (1769497765) is equal to previous stop arrival_time 08:09:25 (1769497765) - times must increase between two sequential stops
stop_time_update departure time is before arrival time E025 2 errors
Within the same stop_time_update, arrival and departures times can be the same, or the departure time can be later than the arrival time - the departure time should never come before the arrival time.
Sample errors
- trip_id 1-691666964 stop_sequence 19 departure_time 08:08:20 (1769497700) is less than the same stop arrival_time 08:09:01 (1769497741) - departure time must be equal to or greater than arrival time
- trip_id 1-779419664 stop_sequence 3 departure_time 08:08:59 (1769497739) is less than the same stop arrival_time 08:09:00 (1769497740) - departure time must be equal to or greater than arrival time
