[Plugin: Translate This Button] translateth.is server down – plugin doesn't work

I noticed this morning that the Translate This button on my site is no longer working. Upon further investigation, I also found that the server at http://www.translateth.is seems to be down — or is simple forwarding all traffic to Google. I wonder — is this service/plugin now defunct?

Thanks,
