... I've set up extra solo pool nodes so the same conditions as the solo.ckpool.org (ie solo mine to your bitcoin address)
First runs diff of 2048:
s4.ckpool.org:3333
Second starts at diff 1 like ghash would:
s4.ckpool.org:3334
Bear in mind that ckpool adjusts diff VERY quickly so it may still work okay.
Are there still S4 nodes?
