As part of an update to XCN, Poloniex will undergo scheduled maintenance beginning on May 20th at 01:00 UTC. We expect the maintenance to take 2 hours.
During the maintenance period, the site will be offline and trading will be suspended. After maintenance, 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.
We will keep you updated throughout each maintenance period on our Support Twitter account.
