@idefix37 this has nothing to do with the offline stations. Meanwhile, some of them seems to be gone now without any notice. Maybe they are from saveecobot. Thats all i figured out currently and i am woundering that this info seems to be of no interest at all.

I figured out that many radiation sensors are very high but down since some days around Prypiat, the famous public known location of the nuclear plant Tschernobyl.

I don't know who is responsible there but this is something that should be analyzed why the measurement is down since 6 days now.
