Where are you working from?  Maybe Huobi servers are working better in some countries than others? MAybe Chinesse are not having those big problems and for that we dont see any information and complaining anywhere?
Im in Europe and since Christmas, Huobi servers are a total Hell...  Almost imposible work there..  
Page fauil daily, log fail, Depth fail (for me set depth to 1 is very important for trade bitcoins, in depth 0 i see nothing in orderbook..)  And finally, you get stuck many times while buying/selling in a enormeus Lag..  
As i said.. Almost imposible toi work there..  

Anyone has some info or posible solutions?  Maybe some proxi or some DNS that would help?
