i opened a ticket and the support said:

"Thank you for getting in touch with us about your deposit.
I apologize for the inconvenience this may have caused you. The IOC wallet has been taken offline temporarily. Our technical support team is working on an update and we are unable to view deposits, process withdrawals, or generate a deposit address. Once wallet is out of maintenance mode, all pending transactions will post in the order that they are received.
We greatly appreciate your patience and understanding as we get the wallet back online and get the coins moving to your account.
If you have further questions, please feel free to connect.".
