Damn... how long was IcyHash offline? I was sleeping...
Normally I would set --failover-only pools but NONE OF THESE DAMN POOLS WORKED PROPERLY.
Failover pool mode doesn't work when icyhash doesn't actually go offline.
No, we were submitting valid shares and probably even valid blocks. They just never made it anywhere. Failover pool wouldn't have done anything.
So when it should have taken something like 4,000 shares to find a block, it took us 62,000. Several times!
When it should have taken 65,000 shares, it took 160,000-1,000,000. Several times!!!
This guy could have easily diverted our hashes to another pool, then made it look as though we'd found no blocks. Do you trust what he says?
