Same here. I guess their website has been suspended? We must wait for more information.
It is most likely a bandwidth issue. They were getting many visits at a time from all over the world of people voting.
They are using namecheap hosting and will have to upgrade to a better hosting company and also a better server.
I saw the plan they are most likely on and now I am 100% certain it was a bandwidth issue. They need to get out of that hosting company asap.
If they want to be taken serious they should not be trying to save on cheap hosting...
