It looks like Poloniex is down!
I hope it is not next Mt.Gox crush!!!
Edit: It looks like it is only problem with servers. I hope...
down for a while,and everybody got panic and lost their minds..i think they just got some trouble for a while,and now its going normal,i opened on last night,its also run normally,i think no need to worry about poloniex,they still good exchange.
