I am last use yobit exchange at 1.00AM and deposit some coin but now i am try to access their site it's not work. They did not give any notice!! Anyone know what is the problem?? Already many money lost in cryptopia Exchange!!! 
Works fine on my end yet i do able to access the site without any problems so far, having no connection intervention or errors. This is most likely some issues with your connection.Try to restart your modem and use up cmd and flush up dns and it might work.
