Now my pool hashrate went to 0 kh/s. Something isnt ok on the pool.
try pinging the pool to see how good of a connection you have. What miner software are you using?
Problems like this are usually on your end, not the pools.
am using cgminer.
do you have any accepted shares shown on cgminer?
I had some accepted shares but the poolhashrate didnt go up.
pool hashrate gets an update once in five minutes. and it calculates an average hashrate for last 10 minutes, so if you were mining at 1000kh/s for one minute, you should get 100kh/s shown on the dashboard when stat updates. also, please note that pool counts shares for payouts, not hashrate. thus, if you have your shares counted on dashboard, you'll get paid for them - no matter what hashrate indicator shows.
