Notice that I'm missing about 10 to 20% of the reword for blocks 17846 and 17845, 17842 and 17841, 17837 and 17836. Unlucky or a problem? Some are over hour so luck shouldn't be a problem...
I just noticed one of the workers happily submitting shares while the account page says I submitted nothing for over an hour. I reconnected and normal operation resumed.
I wonder if a hacker figured out how to redirect mining streams.
