I had also some problems with pool connections today. I found then new pool from poland. The pool owner made some nice graphs of the NetHash and PoolHash. It looked like there where some problems for a while with whole network. You can see it in "history" on the graph. Mostlikey there was some updates goin on many pools.
You can check the NetHash here (

soon there should be statistics for the miners too, so we will be able to see, how the things are going on.
BTW. I am not sure, but after few hours in this new pool i found, i have a feeling that i am getting more XDAGs than before.
Check for yourself and see, if there is any difference there. I am quite interested, is it me, or is it just a lucky day.
You can connect to the pool ---> xdag.corpopool.com:443
Hope you will inJOY it.
