Rightbtc.com is currently down and the admin have not released any statement about it, I hope we are safe?
From what I can see it is no longer down, but the all the trading pairs aren't showing up and functioning correctly still. No ANN yet from official sources, I don't think.
Perhaps it's just a temporary maintenance that wasn't scheduled, though it is extremely unprofessional for them to not have released any public statement about this hiatus given that it can affect customer's access to their funds.
With that said, I wouldn't consider RightBTC a trustworthy exchange by any means.
They have had constant withdrawal issues in the past (
here,
here and
here), there is uncertainty as to whether they are a regulated entity, and their support and PR people don't seem to be terribly responsive. I'd avoid using them once they come back online, if I were you.
