As long as the site is down, if you're still interested in trying Arc: http://arclanguage.org/install

Thank you for sharing this during the downtime!

Try Arc goes down under heavy traffic because every page load requires its own sandboxed Arc instance to be running on the server. It only takes a few of these to gobble up all the resources on my Linode 512.

In any case, http://tryarc.org is back online. Thanks for your patience. :)
