Realtime health 2 monitored
All 2 feed records here with a realtime endpoint configured have been sampled by the monitor. Least reliable first. Reachability, how far behind each feed's own timestamp runs, and how much of the scheduled service appears in it. Sampled on a schedule rather than continuously, and it changes no grade.
Across the monitored feeds: median uptime 50.0%, median lag 3s.

Fixes shared across this group
The same fix shows up in more than one agency's top 3 here, often the same export setting or scheduling-software step. Worth raising once with every agency it touches.
Check the trip updates endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request. · Read the fix guide
