Shit...I just check the worker page and found that it offline...
Then I check the shift graph, it show the worker offline since 16 Jan at around 11:00 UTC+8...
But I am now working at office, can't access the miner, need to wait until tonight and see what happen...

I am very worry...
This is the reason why I had to leave kano's pool.. I would love to come back, but the biggest advantage of Slush pool is that I get an E-Mail as soon as one miner goes below a certain hashrate.
@ Kano
You don't happen to have that feature planned for the future, do you? I know a phone app exists that checks the total hashrate. But the variance of the hashrate gets higher the more miners you have, so you can't recognize a dead miner right away.
With slushpool the moment a miner goes offline you're pretty much screwed anyway - scoring goes to 0 within the hour. Good thing about 5Nd - your shares are still being rewarded even if your miner goes offline.
Tonnes of apps available, personally I use Awesome Miner to send me email notifications. 1% of the rewards you've been giving up to Slushpool would more than pay for Awesome Miner, btw.
