I've been connected since Feb 3, 2016 and have now been on-line for 23d 12h 26m. Have a connection percentage of 99.96% and been off-line for 0h 12m. It appears there was only a single outage of 12 minutes a while back.
I have no idea how to read any of the charts they have on their website that pertains to my unit and I'm not sure that I really care either. The main thing is that my data is supposedly helping someone, somewhere with some project. Gee, that is reassuring! Oh well, it was free and this is just another hobby thing that gets connected to my router...
I also noticed that the map where they show my location isn't even close to my actual location. Interestingly it is showing I'm in the middle of the Cottonwood Slough which is a boggy, lowlands areas well south of me near the Carson River.
My stations link follows (if anyone is interested, that is):
