Hi ya all,
It is not a complain, but I have been noticing last months, that every time that pool's hashrate has a huge hop (like >20TH/s) we are experiencing problems of "stolen" blocks or long rounds (>6h). The last 48h is another example. Hope this new hardware Slush implemented is going to kill this glitches with time.
Salute all Slusher's.
It's not a hardware issue on Slush's end. During long rounds, many people will hop to other pools. You'll see a drop in hashing power which means that there's less chance to find a block compounding the problem. Also, the hash rate is fluid meaning it can vary even if no miners came or went. Hardware errors, vardiff, etc. play a factor in determining the hash rate the pool recognizes.
