my site loading extremely slowly

Getting this site live, having problems.
newbesttop10.com

Loading had been just fine – never thought it loaded slowly whatsoever.

Today when I got us and open my site it is very slowly then I use follow some way :
Where I am now:
– All plugins disabled.
– Browser cache cleared
– Verified slow load times with another computer on different network
– Host says there don’t seem to be any problems from their end

Any help appreciated.
