I'm not necessarily saying its an attack I'm just saying statistically there is a very high probability that something is wrong and a very low probability that everything is running normally.
"It must be an awesome block to be taking this long. Tongue"
plenty of blocks are being solved just not by this pool.
SENSE...OF...HUMOR...PLEASE....  Don't get me wrong...it's been 7 hours. I can only imagine that something is up, and I agree with you wholeheartedly. I'm a numbers man myself, so I can say that is this is epically improbable. :-/ I'm totally okay to think that we're under attack, because that means we've attracted some very seriously intelligent adversity. Slush, if this goes much past 9 hours, can you take a look? |

1031774 shares with difficulty 92347.59095209...
That with an exponential distribution and 175 GHash/s yields a 1.5e-5 = 0.0015% chance of not finding a block in 7 hours. That's what, once per 66k blocks? The entire network has solved 119k blocks, so either we've been the unluckiest pool ever today, or something is wrong.
Just my .02 BTC.
[Edit: now 7:13 --> 1.06e-5, or once per 94k blocks...]

Statistically we are all sorts of jacked at the moment. However, we all my might want to consider that maybe its the statistics/my account part of the site that is busted. I'm not sure if there is an external way to see if we are solving blocks, but the idea that maybe just the front end is broken and mining is functioning properly seems more reasonable than an attack or the numbers provided by VPoro. |

Yes we got there  . Don't know if anyone else had this happen but before the "long block" I was only a little away from the payout threshold. I saw a lot of blocks confirmed but my confirmed reward hadn't gone up since, although total reward has. I thought maybe recalculating the confirmed rewards only happened when a new block was solved but that doesn't seem to have happened yet after a few blocks have been solved since. |

Payouts are currently stopped due to some problems. I'll solve it during day.

My unconfirmed rewards won't get confirmed, I've been waiting for a day now. What's happening?

100% cfd right now.
There is no such thing, unless you are rounding. CFD cannot reach 100%, it can only approach it. |

That's why you can't calculate required time for 100% |

Today's 1.1mil round was really crazy. Hope we will have better luck now  . All payments were processed before few minutes, I'm very sorry for troubles. I had suspect for some bug in the payment system, so I stopped transfers until some investigation. Automatic payments are turned on again. |

Given the last few days of DDos attack, 1.1 mil rounds, payment system issues, I don't envy your job slush. Again, thanks for the hard work |

Oddly ... deepbit.net hasn't updated my payout amount in a few hours. What is up with that? Is something going on with deepbit or is refreshing the browser resetting the "1 hour"? I was trying to explain to my Wife how this all worked [and to explain why the fans in the office are louder than normal] and have been trying to show her the increase ... and it never increases  |

In proportional mode your balance is updated only if block was found during that hour; some blocks take more than a hour to find. In pay-per-share mode your balance is incremented even if block wasn't found. |

I notice that some have take almost three hours to run today, so I shouldn't be surprised then |

Hey Slush, maybe I'm blind but why is there no password change feature on the site? I had to use the "forgot password" feature which works fine but it would be kinda cool if you had something already like that in the control panel that worked just the same. Also a security question upon password reset would be a good idea I think.

Hi slush,
Any plans to add some extra data to the JSON API, particularly as it relates to individual worker stats (shares completed, score, last share received, and found blocks)?
I'm working on building an overview page where I can estimate the BTC (and USD at current rate) each rig has generated, offset by cost of electricity and build cost so I can track how long til my multiple rigs pay themselves off. Those 4 stats for each worker added to the API would make it completely automated, and the information is already being tracked on the profile page.

Hi slush, no big deal but I noticed that since around the time of the DOS attack the system daily reward graph seems stuck.

"There is no such thing, unless you are rounding. CFD cannot reach 100%, it can only approach it."
I think, gentlemen you are making an bad assumption. You assume that a person in the pool will report a winning hash...
If you were a miserable little troll who wanted to interfere with a mining pool what is the worst thing you could do?
I think they have joined your pools and are taking out work but not reporting the winning hashes (hashes that meets full difficulty). This will make your pools think that it has assigned the work for the as yet unknown winning hash so it never reassigns it to a new worker. If they manage to do that on both pools they can send over 300 Gh/s on a wild goose chase, successfully crippling half of the total network capacity, slowing down the solve rates (long term lowering the difficulty at the pools expense?), and frustrating people in the pools.
The worst thing is they still get paid for working against the pools, because they do report hashes of lesser difficulty. Granted they would need a good bit of hash power but they likely have that otherwise why bother attacking the pools.
Just my guess based on the recent unusual pool behavior.
