There's only one server for all to play on that I know of.
And who knows why it went down.
For all we know it could have been overloaded and nobody has seen it yet.
The company is pretty small. So it could take time to reset everything.
There's a ton of info so backing up the database could take a while as well.
Or maybe they are asleep and don't know.
They should sign up for a web service that alerts them when it's down.
