My rig switched over to timetravel sometime this morning, but while I had benchmarked my four 1070s at about 90 MH/s (using tp-ccminer) and was seeing ~87 MH/s when I checked just now, zpool is only showing 500 kH/s or less.  The 24-hour balance graph has definitely leveled off over the past few hours, compared to its usual rate of growth.  Is this an issue with the pool or with the mining software?  (I've disabled timetravel in the meantime; the rig's gone back to mining tribus.)
