I was just about to post the same thing. It's been down for quite a while, the whole time I was at work I couldn't log on with the smart phone. Now I got home and no payments have made it to my wallet. It looks like they are still collecting our coins as they get mined, but not allowing anyone to log on or get paid. I hope they didn't just steal hundreds of thousands of coins.....
It sucks to abandon ship since the difficulties are quite reasonable now, but we may just be donating our coins to the hashstrike admin. It's hard to tell since there's no info on their site.
I just switched to my backup pool - just in case... No payouts for around 6 hours.
Stick with them guys we had the same issue after launch, they are finding blocks and recording them, there just not showing up for you in the block section or your accrued earnings for the period, but they will catch up and show up eventually, after it catches up the query time decides to somersaults to :-), we even paid out double noble when this happened, that was new lol.
