From now - rather than yesterday - the actual block history is as the web site says:
https://kano.is/index.php?k=pblocks5 days - 0 blocks
6 days - 1 block
7 days - 2 blocks
13 days - 3 blocks
17 days - 5 blocks
lots and lots more blocks ...
Oh well, lets hope we get more much closer to the expected time soon.
With your current round, the probability of finding exactly 0 blocks in 7 days at 1.08PH is: 2.24%... based on Bitcoin's poisson distribution... it's not very probable to get the big swings your pool is having.. it's very unlikely... you sure you didn't screw anything up?
