It is loading normally in my chrome browser, which browser you are using?
You can either try different browser or you can check does the problem exist on incognito mode or not. If it doesn't exist in incognito mode than you better clear your browser cache and try again.
Poloniex is working properly too on my rog laptop with a stable internet. I encounter that problem too when i used my computer on my office because the internet is secured and and has only limited connection. I think OP chrome is just a little bit out dated if he is using a free internet connection. Or some plug ins on his browser that interupting the data transfer.
