Doesn't look like it's under maintenance anymore. I created a trade (without sending any coins, thus not completing it) just now.
Honestly, I was shocked, in a good way, when I read that this exchange does not require KYC. Because I know that ChangeNOW requires KYC, but OP will not enforce it on this exchange. It will be very good for the regulars around here, just as long as shady entities don't learn about this site and use it for money laundering.
