i hope it will works soon. but it works very slow try to take another wallet. here we have to transact money and receiving in this process it can take more time so we have to choose in that place another wallet good for us. actually i worked with polonix but it can not did good performs. so i have to trying to take another wallet.
Poloniex didn't experience any downtime at the last few days, if you are having troubles you should be checking your local network.
Anyway seems like tickets delay are a very common problem in Poloniex exchange, support is terrible, if you are not Dan Bilzerian who can twit to polo on twitter, you can't really get in touch with them.
Also, any request to increase the regular limit of 2000$ to 25000$ is not being answered for a very long time.
However, something has change lately: the mobile site doesn't work as good as in the past, the login page sends you in a wrong place.
But this also means something: they are still alive and they work on the website
I hope that their support will become more functional too before they fall behind.
