Today, on Thursday, June 6, the Poloniex Cryptocurrency Exchange will go offline for several hours due to the technical work that will begin at 14:00 UTC.
We expect this to take several hours. During that time Poloniex will be offline and trading will be suspended. Assets on the exchange will be secure during maintenance. We do not plan to cancel open orders. When Poloniex is back online, markets will be in post-only mode for a short time before we reopen trading. During this time, you can cancel open orders and create new orders, but no orders will be filled. Open margin positions will not be affected during this upgrade. They will remain open. After the site is back online, we will open markets in post-only mode. After the order books have refilled, we will reopen trading. After prices have stabilized, we will resume margin calls, and will then begin automated liquidations for accounts breaching maintenance margin requirements a short while after margin calls have resumed.

Some time ago Circle, operator of the Poloniex exchange, cut 10% of staff due to tight regulation of the crypto industry in the United States.
