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

Errors
Sequential stop_time_update times are not increasing E022 2 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 4 stop_sequence 14 arrival_time 07:34:33 (1772001273) is equal to previous stop departure_time 07:34:33 (1772001273) - times must increase between two sequential stops
- trip_id 5 stop_sequence 14 arrival_time 07:56:31 (1772002591) is equal to previous stop departure_time 07:56:31 (1772002591) - times must increase between two sequential stops

Previous validations
Here is a recap of all the error types encountered over the last 30 days.
| Error ID | Description | Errors count | Number of occurences |
|---|---|---|---|
| W001 | Timestamps should be populated for all elements | 14,308 | 25 times (86 % of validations) |
| W002 | vehicle_id should be populated for TripUpdates and VehiclePositions | 12,616 | 25 times (86 % of validations) |
| E025 | 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. | 58 | 23 times (79 % of validations) |
| E022 | stop_time_update arrival/departure times between sequential stops should always increase - they should never be the same or decrease. | 122 | 20 times (69 % of validations) |
| E045 | If GTFS-rt stop_time_update contains both stop_sequence and stop_id, the values must match the GTFS data in stop_times.txt | 1 | 1 times (3 % of validations) |
