Data Feed / Feeder Check-in

What does it mean when the Feeder Check-in is live, but the Data Feed isn’t?

Data Feed: Today - about an hour ago
Feeder Check-in: Live - 3 minutes ago

piaware is connected to the FlightAware servers, but no ADS-B data is being received; check your antenna etc.

(alternatively, stats processing is running behind realtime, but that should be OK at the moment)
