We test this resource download availability every hour by making an HTTP 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.

Errors

stop_times_updates not strictly sorted E002 2 errors

stop_time_updates for a given trip_id must be strictly sorted by increasing stop_sequence

Sample errors

trip_id Dim2_3586624 stop_sequence [15, 16, 17, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27] is not strictly sorted by increasing stop_sequence
trip_id Dim2_3586623 stop_sequence [15, 16, 17, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27] is not strictly sorted by increasing stop_sequence

Sequential stop_time_update times are not increasing E022 36 errors

stop_time_update arrival/departure times between sequential stops should always increase - they should never be the same or decrease.
