Seems like the total amount of aircraft and positions reported has been reset somewhere between now and approx. an hour ago. its currently on 3572 positions vs 65 aircraft. (23:00h)
Around 2900 aircraft where in todays statistics around 17:00h (CET)
Anything going on? as this will be very bad for my average 
Same here.
Same here, went from 60K+ and 360 aircraft to 12K and 97 aircraft around 2300GMT
Looks like NO data is being added to the Aircraft tracks as well from the ADS-B stations
An hour ago, we had to restart one of the backend servers that accepts data from the ADS-B feeder network due to some performance problems. We believe it should be back online now.
I see the tracks coming back.
My numbers (tracked automagically) took a dive for 2200 UTC but were back in line at 2300.
Thanks to all the folks who work to keep things going!
