Bad Luck is Just Bad.
Are we sure there isn't something going on with the backend re:internet access or the nodes pier connections?
Believe me this always goes through an operators mind during long rounds. Paranoia sets in. I have checked and things are fine. We're solving namecoin blocks at a normal rate for example. We're just not finding hashes close enough to the bitcoin target. The best hash we've found so far is:
00000000000001d26460346f49a03d529a843b1603e90507824582f2edb98b7f <= so far
00000000000001AA3D0000000000000000000000000000000000000000000000 <= bitcoin target
We've had a bunch close to that but nothing over. Currently luck is around 19%. We've had worse (about 14% I think). I'm sure other pool operators have had worse too. OzCoin had a 100+ million share round recently. It's definitely not the best timing just as we switch to DGM scaring a bunch of high hash rate miners off unfortunately but what can you do.
