Just my luck... In search for a good way to build my new portfolio website, I stumbled upon ZENphoto... and now the site tells me "there's an upgrade going".

Forgive me for being cynical, but I've seen too many websites telling me to "try later" for MONTHS (sometimes years) so I'd like to ask here:

When will the site be back online?

It is there. It was just shortly closed. Sorry for the confusion.
