was it forked or was it a hard fork?
Too much hash at dedicated pools
usually 60-70% of total
Update on dedicated pool:
There was a fork on the blockchain. All pools affected. We worked directly with the devs. 6 blocks orphaned, but we are on the correct chain now. Whew

were individual wallets affected? I just downloaded a new one and ran it, now im staking every second or so. and my transaction hasnt gone through just says unclaimed on the blackchain
I requested a payout from Bittrex just before all this happened (literally minutes before). My coins took 30 minutes to get to my wallet (compared to usually seconds to a minute). After that, they sat in the "Unconfirmed" balance section...for more than an hour. So, I deleted everything in %appdata%\Cloakcoin (except my wallet) and just redownloaded the block chain. My coins then confirmed.
My guess is if you have any individual wallet issues, either wait a few minutes until this gets sorted out, or just try downloaded the block chain again. It's only ~9,000+ blocks anyway. Doesn't take that long.
