So I have a question, did something happen at 12:59:32 UTC time on the 23'rd? For some reason, I dropped about 10TH and I noticed one of my S9's was only dishing out around 4TH. I finally noticed and rebooted this day and it looks like it is climbing back up. I did get an email saying my hash was low this morning, that's what gave me an inclination something was up.
