Top three things to fix
Ask your AVL vendor why the feed stopped advancing; the GTFS-Realtime header timestamp should move forward on every publish.
The realtime feed's last update was about 1 hours old when sampled. A realtime feed this far behind has effectively stopped. Riders see buses that already left, or apps quietly fall back to the schedule while still showing a live label.
Effort: A vendor support ticket; treat it as a feed outage.
Re-generate shape distances in your export; flag to your vendor if it persists.
Some trips have stop times whose distances along the route go backwards. Apps can show buses jumping backwards or mis-order stops.
Effort: Usually an export-tool fix, not hand editing.
Review the rule documentation for 'block_trips_with_overlapping_stop_times' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Block trips with overlapping stop times (flagged by the MobilityData validator). See the linked rule for what this affects.
Effort: Varies.
