Both deicated and chickenstrips have this msg up:

We are investingating issues in the backend. Your shares and hashrate are safe and we will fix things ASAP.

Findblocks disabled, new blocks will currently not show up in the frontend
Blockupdate disabled, blocks and transactions confirmations are delayed
Payouts disabled, you will not receive any coins to your offline wallet for the time being

Are they owned by the same crowd ? Or issue with the coin ?
