AFAIK they had issues with their monero node sync and it has been solved. I had a warning on kycnot.me for this, but I have now just removed it since I just tested and I was able to withdraw and exchange XMR just fine.

Also, for what I know, they had a ddos attack and their site was unresponsive (for what I also put a warning on kycnot.me the moment I became aware of the issue), seems like the attack is over, as the site was responsive when I was testing a few hours ago.
