The Nubits peg has been broken for at least 12 days now. It is currently at $0.258 instead of the $1.00 like it is supposed to be. It is unclear to me if they will ever regain the peg. Their main developer, the pseudonymous "Jordan Lee" has gone MIA. He was last seen on the Nubits forums 9 days ago. That doesn't exactly inspire confidence, but the Nubits/B&C Exchange community is scrambling to replace him and remedy the situation. We shall see if those efforts are successful... this thread breaks down the Nubits peg failure pretty well, and the ensuing drama that has unfolded:

It is still going strong since before September of 2014, and it is currently valued at $1.01
Nubits is back to $0.88 on bittrex and $0.79 on poloniex, so it looks to me like a recovery is in progress.
You never know if something works until you test it to failure, so this makes for a vote of confidence for Nubits and it's community if the recovery continues.
