what happened to wp-recaptcha?

I have no idea what happened to this WordPress plugin.  The WordPress website indicates that it is not a valid plugin address anymore.

And the developers website is missing the DNS entry, so it’s not coming up.

For now, I’ve uploaded my latest copy of the “wp-recaptha” plugin from one of my sites.  Though I’m hesitant about continuing to use it until I know why it has disappeared.  Any information is welcome.
