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 14 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 1288 stop_sequence 15 arrival_time 07:54:21 (1768805661) is equal to previous stop departure_time 07:54:21 (1768805661) - times must increase between two sequential stops
- trip_id 1285 stop_sequence 8 arrival_time 07:58:09 (1768805889) is equal to previous stop departure_time 07:58:09 (1768805889) - times must increase between two sequential stops
- trip_id 1271 stop_sequence 5 arrival_time 07:48:10 (1768805290) is less than previous stop arrival_time 08:15:16 (1768806916) - times must increase between two sequential stops
- trip_id 1271 stop_sequence 5 arrival_time 07:48:10 (1768805290) is less than previous stop departure_time 08:15:16 (1768806916) - times must increase between two sequential stops
- trip_id 1271 stop_sequence 5 departure_time 07:48:11 (1768805291) is less than previous stop departure_time 08:15:16 (1768806916) - times must increase between two sequential stops
stop_time_update departure time is before arrival time E025 3 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 44 stop_sequence 17 departure_time 08:12:02 (1768806722) is less than the same stop arrival_time 08:12:19 (1768806739) - departure time must be equal to or greater than arrival time
- trip_id 812 stop_sequence 13 departure_time 08:12:02 (1768806722) is less than the same stop arrival_time 08:12:17 (1768806737) - departure time must be equal to or greater than arrival time
- trip_id 1124 stop_sequence 7 departure_time 08:12:01 (1768806721) is less than the same stop arrival_time 08:12:07 (1768806727) - departure time must be equal to or greater than arrival time
