I read that other people also having this problem sometimes, but now i'm experienced this myself.
One of my miners config is suddenly changed to
stratum+tcp://bj.ltc1btc.com:9999 pcfli.nm
stratum+tcp://stratum.f2pool.com:3333 pcfli2.nm
stratum+tcp://stratum.mining.eligius.st:3334 1GwHVTfV3cGMkZXFF36fhzhNbPhyy7TcQr
From the pool hashrate graph it looks like this event was around 12hrs ago.
I already submitted now the pool settings change request on that miner, but also would like to know how this event would be compensated.
will count to your downtime, it is my own mining setting, it is also the mining setting before give the miner to you
maybe they automatically back to the initial setting by accident
