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.

GTFS-rt stop_time_update stop_sequence and stop_id do not match GTFS E045 1,840 errors

If GTFS-rt stop_time_update contains both stop_sequence and stop_id, the values must match the GTFS data in stop_times.txt

Sample errors
