It went back up sometime between 8-9pm cet

Eth pool is down and it's likely that ETC, MONA and VTC pools are down too as those were down last time when the website was down, all probably running on the same HW.

Looks like you're down again. Two different type so an error in my log.

I've been mining with ethminer here for over a week and I have a stable hashrate. The hashrate displayed by the website differs, sometimes even by +5 compared to my actual hashrate, other times -5. It's definitely based on the shares submitted and accepted, and as the difficulty oscilates, so will your acceptance rate. A 10 minute window is too small I think to make a longterm judgement.

A suggestion would be at the pool operator to probably add an ability to log a larger timeframe, but I understand that this would mean you have to collect and store more data and might not be the most efficient thing to focus at this early in this pools lifetime.

That's a great idea. Also up for testing when needed.

Thanks for the explanation and honesty. +1

Any explanations as to what has caused it and why only some pools were affected, as well as what mitigation can and will be done for the future?

So during your outage last night I was thinking "backup" should your outage not be a short term one time issue. So I wondered where should I point my miner in the interim and after doing my research I came up with another reason why I like your pool: PPLNS, vardiff, EU based. There weren't many other pools that gave me all three, in fact I don't think I found one.

I have a new suggestion.

Sample executables

While some of us more tech savvy people haven no problem setting up our miners and our executables, others less tech savvy people might be lost even following your instructions. How about you share sample executable files (.bat, .exe) on the guidelines, where the only thing people have to change is their wallet address?

Just following up. Now the chart shows 600-700 MH for the past 2 days. Something is really off with the chart.

So I see the hashpower of Ethereum pool jumped by about 0.5GH today, but I am confused by the graph, it says we've been oscilating at 1.6GH for over two days already, but I swear I saw a different graph with oscillation at 1 to 1.2GH earlier this morning.
