zpool down?
Looking into some data centre issues or perhaps its an undetcted ddos.
Will update shortly
with problems of all kinds you could even give out a little info on twitter, so that as miner knows what's going on, that would be a great idea, right? other pools do the same, increasing customer satisfaction enormously; you know there is something happening, there you are on the problem and so on ....

I think that's great, that's the way it should always be; And already most of your customers are satisfied, thank you very much for the fast implementation;
Good luck finding the problem, thanks
