An aside: if you rent hash, point it here, and it causes problems because of the way the lessor set up the machine, who's responsible? NiceScam? No. The lessor? No. It falls on YOU. Not having full control of the hardware you're using is about as smart as not having full control of your wallet.
Mine on!!!
So even though I have my equipment in my facility, I still have questions if it is totally legit and correct (and if bitmain can still get their fingers at it through my firewall)... Obviously the firmware of these suckers is not easy to deal with. My S9 has been mining for 9 months and still no block. Not all that surprising given the difficulty, but makes a person wonder sometimes...
