Suddenly all my data has disappeared for the 4th ??? 
**I’m not bothered about the data **on my Pi since it has only just come online but for information to FlightAware so they know what we are seeing.
Earlier this afternoon (UK), 04 April was showing 3 aircraft seen and 03 April was showing 1157. Picture below shows current status.
same here, I guess they are redoing the 03 and 04 stats.
