Any news about Poloniex Steem deposit/withdraw issue ?

Hey guys,

Since few weeks now poloniex is unavailable to deposit or withdraw steem, do you guys have any idea of what happend ?

message always :
STEEM is currently under maintenance or experiencing wallet/network issues. Deposits and withdrawals will remain disabled until a solution is found, which may require an update from the STEEM team. Any updates must be tested and audited before enabling.

What's the problem ? Any idea on when it will be ok ?

i can't wait to deposit on steemit more steem....

Thanks for your help!
