Yeah reward may be random but I should get like 700 doges per hour average (difficulty of yesterday), It may be more or less somethimes but the difference is big.
Well never had any problems with multipool.us in the past so guess having bad luck
multipool.us is down currently. Well the pools may seem to be up, but website says down it is and suggests using other pools until "Morning".
EDIT: seems to be back up now!
